+# CHANGELOG Automation
+
+We use [changie](https://changie.dev/) to automate `CHANGELOG` generation.  For installation and format/command specifics, see the documentation.
+
+### Quick Tour
+
+- All new change entries get generated under `/.changes/unreleased` as a yaml file
+- `header.tpl.md` contains the contents of the entire CHANGELOG file
+- `0.0.0.md` contains the contents of the footer for the entire CHANGELOG file.  changie looks to be in the process of supporting a footer file the same as it supports a header file.  Switch to that when available.  For now, the 0.0.0 in the file name forces it to the bottom of the changelog no matter what version we are releasing.
+- `.changie.yaml` contains the fields in a change, the format of a single change, as well as the format of the Contributors section for each version.
+
+### Workflow
+
+#### Daily workflow
+Almost every code change we make associated with an issue will require a `CHANGELOG` entry.  After you have created the PR in GitHub, run `changie new` and follow the command prompts to generate a yaml file with your change details.  This only needs to be done once per PR.
+
+The `changie new` command will ensure correct file format and file name.  There is a one to one mapping of issues to changes.  Multiple issues cannot be lumped into a single entry. If you make a mistake, the yaml file may be directly modified and saved as long as the format is preserved.
+
+Note: If your PR has been cleared by the Core Team as not needing a changelog entry, the `Skip Changelog` label may be put on the PR to bypass the GitHub action that blacks PRs from being merged when they are missing a `CHANGELOG` entry.
+
+#### Prerelease Workflow
+These commands batch up changes in `/.changes/unreleased` to be included in this prerelease and move those files to a directory named for the release version.  The `--move-dir` will be created if it does not exist and is created in `/.changes`.
+
+```
+changie batch <version>  --move-dir '<version>' --prerelease 'rc1'
+changie merge
+```
+
+Example
+```
+changie batch 1.0.5  --move-dir '1.0.5' --prerelease 'rc1'
+changie merge
+```
+
+#### Final Release Workflow
+These commands batch up changes in `/.changes/unreleased` as well as `/.changes/<version>` to be included in this final release and delete all prereleases.  This rolls all prereleases up into a single final release.  All `yaml` files in `/unreleased` and `<version>` will be deleted at this point.
+
+```
+changie batch <version>  --include '<version>' --remove-prereleases
+changie merge
+```
+
+Example
+```
+changie batch 1.0.5  --include '1.0.5' --remove-prereleases
+changie merge
+```
+
+### A Note on Manual Edits & Gotchas
+- Changie generates markdown files in the `.changes` directory that are parsed together with the `changie merge` command.  Every time `changie merge` is run, it regenerates the entire file.  For this reason, any changes made directly to `CHANGELOG.md` will be overwritten on the next run of `changie merge`.
+- If changes need to be made to the `CHANGELOG.md`, make the changes to the relevant `<version>.md` file located in the `/.changes` directory.  You will then run `changie merge` to regenerate the `CHANGELOG.MD`.
+- Do not run `changie batch` again on released versions.  Our final release workflow deletes all of the yaml files associated with individual changes.  If for some reason modifications to the `CHANGELOG.md` are required after we've generated the final release `CHANGELOG.md`, the modifications need to be done manually to the `<version>.md` file in the `/.changes` directory.
+- changie can modify, create and delete files depending on the command you run.  This is expected.  Be sure to commit everything that has been modified and deleted.

+The core function of dbt is SQL compilation and execution. Users create projects of dbt resources (models, tests, seeds, snapshots, ...), defined in SQL and YAML files, and they invoke dbt to create, update, or query associated views and tables. Today, dbt makes heavy use of Jinja2 to enable the templating of SQL, and to construct a DAG (Directed Acyclic Graph) from all of the resources in a project. Users can also extend their projects by installing resources (including Jinja macros) from other projects, called "packages."
+
+## dbt-core
+
+Most of the python code in the repository is within the `core/dbt` directory.
+- [`single python files`](core/dbt/README.md): A number of individual files, such as 'compilation.py' and 'exceptions.py'
+
+The main subdirectories of core/dbt:
+- [`adapters`](core/dbt/adapters/README.md): Define base classes for behavior that is likely to differ across databases
+- [`clients`](core/dbt/clients/README.md): Interface with dependencies (agate, jinja) or across operating systems
+- [`config`](core/dbt/config/README.md): Reconcile user-supplied configuration from connection profiles, project files, and Jinja macros
+- [`context`](core/dbt/context/README.md): Build and expose dbt-specific Jinja functionality
+- [`contracts`](core/dbt/contracts/README.md): Define Python objects (dataclasses) that dbt expects to create and validate
+- [`deps`](core/dbt/deps/README.md): Package installation and dependency resolution
+- [`events`](core/dbt/events/README.md): Logging events
+- [`graph`](core/dbt/graph/README.md): Produce a `networkx` DAG of project resources, and selecting those resources given user-supplied criteria
+- [`include`](core/dbt/include/README.md): The dbt "global project," which defines default implementations of Jinja2 macros
+- [`parser`](core/dbt/parser/README.md): Read project files, validate, construct python objects
+- [`task`](core/dbt/task/README.md): Set forth the actions that dbt can perform when invoked
+
+Legacy tests are found in the 'test' directory:
+- [`unit tests`](core/dbt/test/unit/README.md): Unit tests
+- [`integration tests`](core/dbt/test/integration/README.md): Integration tests
+
+### Invoking dbt
+
+The "tasks" map to top-level dbt commands. So `dbt run` => task.run.RunTask, etc. Some are more like abstract base classes (GraphRunnableTask, for example) but all the concrete types outside of task should map to tasks. Currently one executes at a time. The tasks kick off their “Runners” and those do execute in parallel. The parallelism is managed via a thread pool, in GraphRunnableTask.
+
+core/dbt/include/index.html
+This is the docs website code. It comes from the dbt-docs repository, and is generated when a release is packaged.
+
+## Adapters
+
+dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. For testing and development purposes, the dbt-postgres plugin lives alongside the dbt-core codebase, in the [`plugins`](plugins) subdirectory. Like other adapter plugins, it is a self-contained codebase and package that builds on top of dbt-core.
+
+Each adapter is a mix of python, Jinja2, and SQL. The adapter code also makes heavy use of Jinja2 to wrap modular chunks of SQL functionality, define default implementations, and allow plugins to override it.
+
+Each adapter plugin is a standalone python package that includes:
+
+- `dbt/include/[name]`: A "sub-global" dbt project, of YAML and SQL files, that reimplements Jinja macros to use the adapter's supported SQL syntax
+- `dbt/adapters/[name]`: Python modules that inherit, and optionally reimplement, the base adapter classes defined in dbt-core
+- `setup.py`
+
+The Postgres adapter code is the most central, and many of its implementations are used as the default defined in the dbt-core global project. The greater the distance of a data technology from Postgres, the more its adapter plugin may need to reimplement.
+
+## Testing dbt
+
+The [`test/`](test/) subdirectory includes unit and integration tests that run as continuous integration checks against open pull requests. Unit tests check mock inputs and outputs of specific python functions. Integration tests perform end-to-end dbt invocations against real adapters (Postgres, Redshift, Snowflake, BigQuery) and assert that the results match expectations. See [the contributing guide](CONTRIBUTING.md) for a step-by-step walkthrough of setting up a local development and testing environment.
+
+## Everything else
+
+- [docker](docker/): All dbt versions are published as Docker images on DockerHub. This subfolder contains the `Dockerfile` (constant) and `requirements.txt` (one for each version).
+- [etc](etc/): Images for README
+- [scripts](scripts/): Helper scripts for testing, releasing, and producing JSON schemas. These are not included in distributions of dbt, nor are they rigorously tested—they're just handy tools for the dbt maintainers :)

-### tl;dr
- - Macros
- - More control over how models are materialized
- - Minor improvements
- - Bugfixes
- - Connor McArthur
-
-### Macros
-
-Macros are snippets of SQL that can be called like functions in models. Macros make it possible to re-use SQL between models
-in keeping with the engineering principle of DRY (Dont Repeat Yourself). Moreover, packages can expose Macros that you can use in your own dbt project.
-
-For detailed information on how to use Macros, check out the pull request [here](https://github.com/analyst-collective/dbt/pull/245)
-
-
-### Runtime Materialization Configs
-DBT Version 0.6.0 introduces two new ways to control the materialization of models:
-
-#### Non-destructive dbt run [more info](https://github.com/analyst-collective/dbt/issues/137)
-
-If you provide the `--non-destructive` argument to `dbt run`, dbt will minimize the amount of time during which your models are unavailable. Specfically, dbt
-will
- 1. Ignore models materialized as `views`
- 2. Truncate tables and re-insert data instead of dropping and re-creating
-
-This flag is useful for recurring jobs which only need to update table models and incremental models.
-
-```bash
-dbt run --non-destructive
-```
-
-#### Incremental Model Full Refresh [more info](https://github.com/analyst-collective/dbt/issues/140)
-
-If you provide the `--full-refresh` argument to `dbt run`, dbt will treat incremental models as table models. This is useful when
-
-1. An incremental model schema changes and you need to recreate the table accordingly
-2. You want to reprocess the entirety of the incremental model because of new logic in the model code
-
-```bash
-dbt run --full-refresh
-```
-
-Note that `--full-refresh` and `--non-destructive` can be used together!
-
-For more information, run
-```
-dbt run --help
-```
-
-### Minor improvements [more info](https://github.com/analyst-collective/dbt/milestone/15?closed=1)
-
-#### Add a `{{ target }}` variable to the dbt runtime [more info](https://github.com/analyst-collective/dbt/issues/149)
-Use `{{ target }}` to interpolate profile variables into your model definitions. For example:
-
-```sql
--- only use the last week of data in development
-select * from events
-
-{% if target.name == 'dev' %}
-where created_at > getdate() - interval '1 week'
-{% endif %}
-```
-
-#### User-specified `profiles.yml` dir [more info](https://github.com/analyst-collective/dbt/issues/213)
-DBT looks for a file called `profiles.yml` in the `~/.dbt/` directory. You can now overide this directory with
-```bash
-$ dbt run --profiles-dir /path/to/my/dir
-```
-#### Add timestamp to console output [more info](https://github.com/analyst-collective/dbt/issues/125)
-Informative _and_ pretty
-
-#### Run dbt from subdirectory of project root [more info](https://github.com/analyst-collective/dbt/issues/129)
-A story in three parts:
-```bash
-cd models/snowplow/sessions
-vim sessions.sql
-dbt run # it works!
-```
-
-#### Pre and post run hooks [more info](https://github.com/analyst-collective/dbt/issues/226)
-```yaml
-# dbt_project.yml
-name: ...
-version: ...
-
-...

-  - SQL returns > 0 results --> fail
-- dbt-core integration tests
-  - running in Continuous Integration environments

-
-### Custom SQL data tests
-
-Schema tests have proven to be an essential part of a modern analytical workflow. These schema tests validate basic constraints about your data. Namely: not null, unique, accepted value, and foreign key relationship properties can be asserted using schema tests.
-
-With dbt v0.5.4, you can now write your own custom "data tests". These data tests are SQL SELECT statements that return 0 rows on success, or > 0 rows on failure. A typical data test might look like:
-
-```sql
--- tests/assert_less_than_5_pct_event_cookie_ids_are_null.sql
-
--- If >= 5% of cookie_ids are null, then the test returns 1 row (failure).
--- If < 5% of cookie_ids are null, then the test returns 0 rows (success)
-
-with calc as (
-
-    select
-      sum(case when cookie_id is null then 1 else 0 end)::float / count(*)::float as fraction
-    from {{ ref('events') }}
-
-)
-
-select * from calc where fraction < 0.05
-```
-
-To enable data tests, add the `test-paths` config to your `dbt_project.yml` file:
-
-```yml
-name: 'Vandelay Industries`
-version: '1.0'
-
-source-paths: ["models"]
-target-path: "target"
-test-paths: ["tests"]        # look for *.sql files in the "tests" directory
-....
-```
-
-Any `.sql` file found in the `test-paths` director(y|ies) will be evaluated as data tests. These tests can be run with:
-
-```bash
-dbt test # run schema + data tests
-dbt test --schema # run only schema tests
-dbt test --data # run only data tests
-dbt test --data --schema # run schema + data tests
-
-# For more information, try
-dbt test -h
-```
-
-### DBT-core integration tests
-
-With the dbt 0.5.4 release, dbt now features a robust integration test suite. These integration tests will help mitigate the risk of software regressions, and in so doing, will help us develop dbt more quickly. You can check out the tests [here](https://github.com/analyst-collective/dbt/tree/development/test/integration), and the test results [here (linux/osx)](https://circleci.com/gh/analyst-collective/dbt/tree/master) and [here (windows)](https://ci.appveyor.com/project/DrewBanin/dbt/branch/development).
-
-
-### The Future
-
-You can check out the DBT roadmap [here](https://github.com/analyst-collective/dbt/milestones). In the next few weeks, we'll be working on [bugfixes](https://github.com/analyst-collective/dbt/milestone/11), [minor features](https://github.com/analyst-collective/dbt/milestone/15), [improved macro support](https://github.com/analyst-collective/dbt/milestone/14), and  [expanded control over runtime materialization configs](https://github.com/analyst-collective/dbt/milestone/9).

-
-## dbt release 0.5.3
-
-Bugfix release.
-
-Fixes regressions introduced in 0.5.1 and 0.5.2.
-
-### Fixed 0.5.1 regressions
-Incremental models were broken by the new column expansion feature. Column expansion is implemented as
-```sql
-alter table ... add column tmp_col varchar({new_size});
-update ... set tmp_col = existing_col
-alter table ... drop column existing_col
-alter table ... rename tmp_col to existing_col
-```
-
-This has the side-effect of moving the `existing_col` to the "end" of the table. When an incremental model tries to
-```sql
-insert into {table} (
-   select * from tmp_table
-)
-```
-suddenly the columns in `{table}` are incongruent with the columns in `tmp_table`. This insert subsequently fails.
-
-The fix for this issue is twofold:
-
-1. If the incremental model table DOES NOT already exist, avoid inserts altogether. Instead, run a `create table as (...)` statement
-2. If the incremental model table DOES already exist, query for the columns in the existing table and use those to build the insert statement, eg:
-
-```sql
-insert into "dbt_dbanin"."sessions" ("session_end_tstamp", "session_start_tstamp", ...)
-(
-    select "session_end_tstamp", "session_start_tstamp", ...
-    from "sessions__dbt_incremental_tmp"
-);
-```
-
-In this way, the source and destination columns are guaranteed to be in the same order!
-
-### Fixed 0.5.2 regressions
-
-We attempted to refactor the way profiles work in dbt. Previously, a default `user` profile was loaded, and the profiles specified in `dbt_project.yml` or on the command line (`with --profile`) would be applied on top of the `user` config. This implementation is [some of the earliest code](https://github.com/analyst-collective/dbt/commit/430d12ad781a48af6a754442693834efdf98ffb1) that was committed to dbt.
-
-As `dbt` has grown, we found this implementation to be a little unwieldy and hard to maintain. The 0.5.2 release made it so that only one profile could be loaded at a time. This profile needed to be specified in either `dbt_project.yml` or on the command line with `--profile`. A bug was errantly introduced during this change which broke the handling of dependency projects.
-
-### The future
-
-The additions of automated testing and a more comprehensive manual testing process will go a long way to ensuring the future stability of dbt. We're going to get started on these tasks soon, and you can follow our progress here: https://github.com/analyst-collective/dbt/milestone/16 .

-## dbt release 0.5.1
-
-### 0. tl;dr
-
-1. Raiders of the Lost Archive -- version your raw data to make historical queries more accurate
-2. Column type resolution for incremental models (no more `Value too long for character type` errors)
-3. Postgres support
-4. Top-level configs applied to your project + all dependencies
-5. --threads CLI option + better multithreaded output
-
-### 1. Source table archival https://github.com/analyst-collective/dbt/pull/183
-
-Commonly, analysts need to "look back in time" at some previous state of data in their mutable tables. Imagine a `users` table which is synced to your data warehouse from a production database. This `users` table is a representation of what your users look like _now_. Consider what happens if you need to look at revenue by city for each of your users trended over time. Specifically, what happens if a user moved from, say, Philadelphia to New York? To do this correctly, you need to archive snapshots of the `users` table on a recurring basis. With this release, dbt now provides an easy mechanism to store such snapshots.
-
-To use this new feature, declare the tables you want to archive in your `dbt_project.yml` file:
-
-```yaml
-archive:
-    - source_schema: synced_production_data  # schema to look for tables in (declared below)
-      target_schema: dbt_archive             # where to archive the data to
-      tables:                                # list of tables to archive
-        - source_table: users                # table to archive
-          target_table: users_archived       # table to insert archived data into
-          updated_at: updated_at             # used to determine when data has changed
-          unique_key: id                     # used to generate archival query
-
-        - source_table: some_other_table
-           target_table: some_other_table_archive
-           updated_at: "updatedAt"
-           unique_key: "expressions || work || LOWER(too)"
-
-    - source_schema: some_other_schema
-      ....
-```
-
-The archived tables will mirror the schema of the source tables they're generated from. In addition, three fields are added to the archive table:
-
-1. `valid_from`: The timestamp when this archived row was inserted (and first considered valid)
-1. `valid_to`: The timestamp when this archived row became invalidated. The first archived record for a given `unique_key` has `valid_to = NULL`. When newer data is archived for that `unique_key`, the `valid_to` field of the old record is set to the `valid_from` field of the new record!
-1. `scd_id`: A unique key generated for each archive record. Scd = [Slowly Changing Dimension](https://en.wikipedia.org/wiki/Slowly_changing_dimension#Type_2:_add_new_row).
-
-dbt models can be built on top of these archived tables. The most recent record for a given `unique_key` is the one where `valid_to` is `null`.
-
-To run this archive process, use the command `dbt archive`. After testing and confirming that the archival works, you should schedule this process through cron (or similar).
-
-### 2. Incremental column expansion https://github.com/analyst-collective/dbt/issues/175
-
-Incremental tables are a powerful dbt feature, but there was at least one edge case which makes working with them difficult. During the first run of an incremental model, Redshift will infer a type for every column in the table. Subsequent runs can insert new data which does not conform to the expected type. One example is a `varchar(16)` field which is inserted into a `varchar(8)` field.
-In practice, this error looks like:
-
-```
-Value too long for character type
-DETAIL:
-  -----------------------------------------------
-  error:  Value too long for character type
-  code:      8001
-  context:   Value too long for type character varying(8)
-  query:     3743263
-  location:  funcs_string.hpp:392
-  process:   query4_35 [pid=18194]
-  -----------------------------------------------
-```
-
-With this release, dbt will detect when column types are incongruent and will attempt to reconcile these different types if possible. Specifically, dbt will alter the incremental model table schema from `character varying(x)` to `character varying(y)` for some `y > x`. This should drastically reduce the occurrence of this class of error.
-
-### 3. First-class Postgres support https://github.com/analyst-collective/dbt/pull/183
-
-With this release, Postgres became a first-class dbt target. You can configure a postgres database target in your `~/.dbt/profiles.yml` file:
-
-```yaml
-warehouse:
-  outputs:
-    dev:
-      type: postgres    # configure a target for Postgres
-      host: localhost
-      user: Drew
-      ....
-  run-target: dev
-```
-
-While Redshift is built on top of Postgres, the two are subtly different. For instance, Redshift supports sort and dist keys, while Postgres does not! dbt will use the database target `type` parameter to generate the appropriate SQL for the target database.
-
-### 4. Root-level configs https://github.com/analyst-collective/dbt/issues/161
-
-Configurations in `dbt_project.yml` can now be declared at the `models:` level. These configurations will apply to the primary project, as well as any dependency projects. This feature is particularly useful for setting pre- or post- hooks that run for *every* model. In practice, this looks like:
-
-```yaml
-name: 'My DBT Project'
-
-models:
-    post-hook:
-        - "grant select on {{this}} to looker_user"     # Applied to 'My DBT Project' and 'Snowplow' dependency
-    'My DBT Project':
-        enabled: true
-    'Snowplow':
-        enabled: true
-```
-
-### 5. --threads CLI option https://github.com/analyst-collective/dbt/issues/143
-
-The number of threads that DBT uses can now be overridden with a CLI argument. The number of threads used must be between 1 and 8.
-
-```bash
-dbt run --threads 1    # fine
-# or
-dbt run --threads 4    # great
-# or
-dbt run --threads 42    # too many!
-```
-
-In addition to this new CLI argument, the output from multi-threaded dbt runs should be a little more orderly now. Models won't show as `START`ed until they're actually queued to run. Previously, the output here was a little confusing. Happy threading!
-
-### Upgrading

-To upgrade to version 0.5.1 of dbt, run:

-### 0. tl;dr
-
-- use a temp table when executing incremental models
-- arbitrary configuration (using config variables)
-- specify branches for dependencies
-- more & better docs
-
-### 1. new incremental model generation https://github.com/analyst-collective/dbt/issues/138
-
-In previous versions of dbt, an edge case existed which caused the `sql_where` query to select different rows in the `delete` and `insert` steps. As a result, it was possible to construct incremental models which would insert duplicate records into the specified table. With this release, DBT uses a temp table which will 1) circumvent this issue and 2) improve query performance. For more information, check out the GitHub issue: https://github.com/analyst-collective/dbt/issues/138
-
-### 2. Arbitrary configuration https://github.com/analyst-collective/dbt/issues/146
-
-Configuration in dbt is incredibly powerful: it is what allows models to change their behavior without changing their code. Previously, all configuration was done using built-in parameters, but that actually limits the user in the power of configuration.
-
-With this release, you can inject variables from `dbt_project.yml` into your top-level and dependency models. In practice, variables work like this:
-
-```yml
-# dbt_project.yml
-
-models:
-  my_project:
-    vars:
-      exclude_ip: '192.168.1.1'
-```
-
-```sql
--- filtered_events.sql
-
--- source code
-select * from public.events where ip_address != '{{ var("exclude_ip") }}'
-
--- compiles to
-select * from public.events where ip_address != '192.168.1.1'
-```
-
-The `vars` parameter in `dbt_project.yml` is compiled, so you can use jinja templating there as well! The primary use case for this is specifying "input" models to a dependency.
-
-Previously, dependencies used `ref(...)` to select from a project's base models. That interface was brittle, and the idea that dependency code had unbridled access to all of your top-level models made us a little uneasy. As of this release, we're deprecating the ability for dependencies to `ref(...)` top-level models. Instead, the recommended way for this to work is with vars! An example:
-
-```sql
--- dbt_modules/snowplow/models/events.sql
-
-select * from {{ var('snowplow_events_table') }}
-```
-
-and
-
-```yml
-models:
-  Snowplow:
-    vars:
-      snowplow_events_table: "{{ ref('base_events') }}"
-```
-
-This effectively mirrors the previous behavior, but it much more explicit about what's happening under the hood!
-
-### 3. specify a dependency branch https://github.com/analyst-collective/dbt/pull/165
-
-With this release, you can point DBT to a specific branch of a dependency repo. The syntax looks like this:
-
-```
-repositories:
-    - https://github.com/analyst-collective/dbt-audit.git@development # use the "development" branch
-```
-
-### 4. More & Better Docs!

-Check em out! And let us know if there's anything you think we can improve upon!
-
-
-### Upgrading
-
-To upgrade to version 0.5.0 of dbt, run:
-
-``` bash
-pip install --upgrade dbt
-```
-
----
-
-### 0. tl;dr
-
-- `--version` command
-- pre- and post- run hooks
-- windows support
-- event tracking
-
-
-### 1. --version https://github.com/analyst-collective/dbt/issues/135
-
-The `--version` command was added to help aid debugging. Further, organizations can use it to ensure that everyone in their org is up-to-date with dbt.
-
-```bash
-$ dbt --version
-installed version: 0.4.7
-   latest version: 0.4.7
-Up to date!
-```
-
-### 2. pre-and-post-hooks https://github.com/analyst-collective/dbt/pull/147
-
-With this release, you can now specify `pre-` and `post-` hooks that are run before and after a model is run, respectively. Hooks are useful for running `grant` statements, inserting a log of runs into an audit table, and more! Here's an example of a grant statement implemented using a post-hook:
-
-```yml
-models:
-  my_project:
-    post-hook: "grant select on table {{this}} to looker_user"
-    my_model:
-       materialized: view
-    some_model:
-      materialized: table
-      post-hook: "insert into my_audit_table (model_name, run_at) values ({{this.name}}, getdate())"
-```
-
-Hooks are recursively appended, so the `my_model` model will only receive the `grant select...` hook, whereas the `some_model` model will receive _both_ the `grant select...` and `insert into...` hooks.
-
-Finally, note that the `grant` statement uses the (hopefully familiar) `{{this}}` syntax whereas the `insert` statement uses the `{{this.name}}` syntax. When DBT creates a model:
- - A temp table is created
- - The original model is dropped
- - The temp table is renamed to the final model name
-
-DBT will intelligently uses the right table/view name when you invoke `{{this}}`, but you have a couple of more specific options available if you need them:
-
-```
-{{this}} : "schema"."table__dbt_tmp"
-{{this.schema}}: "schema"
-{{this.table}}: "table__dbt_tmp"
-{{this.name}}: "table"
-```
-
-### 3. Event tracking https://github.com/analyst-collective/dbt/issues/89
-
-We want to build the best version of DBT possible, and a crucial part of that is understanding how users work with DBT. To this end, we've added some really simple event tracking to DBT (using Snowplow). We do not track credentials, model contents or model names (we consider these private, and frankly none of our business). This release includes basic event tracking that reports 1) when dbt is invoked 2) when models are run, and 3) basic platform information (OS + python version). The schemas for these events can be seen [here](https://github.com/analyst-collective/dbt/tree/development/events/schemas/com.fishtownanalytics)
-
-You can opt out of event tracking at any time by adding the following to the top of you `~/.dbt/profiles.yml` file:
-
-```yaml
-config:
-    send_anonymous_usage_stats: False
-```
-
-### 4. Windows support https://github.com/analyst-collective/dbt/pull/154

-dbt v0.4.1 provides improvements to incremental models, performance improvements, and ssh support for db connections.
-
-### 0. tl;dr
-
-- slightly modified dbt command structure
-- `unique_key` setting for incremental models
-- connect to your db over ssh
-- no more model-defaults
-- multithreaded schema tests
-
-If you encounter an SSL/cryptography error while upgrading to this version of dbt, check that your version of pip is up-to-date
-
-```bash
-pip install -U pip
-pip install -U dbt
-```
-
-### 1. new dbt command structure https://github.com/analyst-collective/dbt/issues/109
-```bash
-# To run models
-dbt run # same as before
-
-# to dry-run models
-dbt run --dry # previously dbt test
-
-# to run schema tests
-dbt test # previously dbt test --validate
-```
-
-### 2. Incremental model improvements https://github.com/analyst-collective/dbt/issues/101
-
-Previously, dbt calculated "new" incremental records to insert by querying for rows which matched some `sql_where` condition defined in the model configuration. This works really well for atomic datasets like a clickstream event log -- once inserted, these records will never change. Other datasets, like a sessions table comprised of many pageviews for many users, can change over time. Consider the following scenario:
-
-User 1 Session 1 Event 1 @ 12:00
-User 1 Session 1 Event 2 @ 12:01
--- dbt run --
-User 1 Session 1 Event 3 @ 12:02
-
-In this scenario, there are two possible outcomes depending on the `sql_where` chosen: 1) Event 3 does not get included in the Session 1 record for User 1 (bad), or 2) Session 1 is duplicated in the sessions table (bad). Both of these outcomes are inadequate!
-
-With this release, you can now add a `unique_key` expression to an incremental model config. Records matching the `unique_key` will be `delete`d from the incremental table, then `insert`ed as usual. This makes it possible to maintain data accuracy without recalculating the entire table on every run.
-
-The `unique_key` can be any expression which uniquely defines the row, eg:
-```yml
-sessions:
-  materialized: incremental
-  sql_where: "session_end_tstamp > (select max(session_end_tstamp) from {{this}})"
-  unique_key: user_id || session_index
-```
-
-### 3. Run schema validations concurrently https://github.com/analyst-collective/dbt/issues/100
-
-The `threads` run-target config now applies to schema validations too. Try it with `dbt test`
-
-### 4. Connect to database over ssh https://github.com/analyst-collective/dbt/issues/93
-
-Add an `ssh-host` parameter to a run-target to connect to a database over ssh. The `ssh-host` parameter should be the name of a `Host` in your `~/.ssh/config` file [more info](http://nerderati.com/2011/03/17/simplify-your-life-with-an-ssh-config-file/)
-
-```yml
-warehouse:
-  outputs:
-    dev:
-      type: redshift
-      host: my-redshift.amazonaws.com
-      port: 5439
-      user: my-user
-      pass: my-pass
-      dbname: my-db
-      schema: dbt_dbanin
-      threads: 8
-      ssh-host: ssh-host-name  # <------ Add this line
-  run-target: dev
-```
-
-### Remove the model-defaults config https://github.com/analyst-collective/dbt/issues/111
-
-The `model-defaults` config doesn't make sense in a dbt world with dependencies. To apply default configs to your package, add the configs immediately under the package definition:
-
-```yml
-models:
-    My_Package:
-        enabled: true
-        materialized: table
-        snowplow:
-            ...
-```
-

-
-## dbt v0.4.0
-
-dbt v0.4.0 provides new ways to materialize models in your database.
-
-### 0. tl;dr
- - new types of materializations: `incremental` and `ephemeral`
- - if upgrading, change `materialized: true|false` to `materialized: table|view|incremental|ephemeral`
- - optionally specify model configs within the SQL file
-
-### 1. Feature: `{{this}}` template variable https://github.com/analyst-collective/dbt/issues/81
-The `{{this}}` template variable expands to the name of the model being compiled. For example:
-
-```sql
--- my_model.sql
-select 'the fully qualified name of this model is {{ this }}'
--- compiles to
-select 'the fully qualified name of this model is "the_schema"."my_model"'
-```
-
-### 2. Feature: `materialized: incremental` https://github.com/analyst-collective/dbt/pull/90
-
-After initially creating a table, incremental models will `insert` new records into the table on subsequent runs. This drastically speeds up execution time for large, append-only datasets.
-
-Each execution of dbt run will:
- - create the model table if it doesn't exist
- - insert new records into the table
-
-New records are identified by a `sql_where` model configuration option. In practice, this looks like:
-
-```yml
-
-sessions:
-    materialized: incremental
-    sql_where: "session_start_time > (select max(session_start_time) from {{this}})"
-```
-
-There are a couple of new things here. Previously, `materialized` could either be set to `true` or `false`. Now, the valid options include `view`, `table,` `incremental`, and `ephemeral` (more on this last one below). Also note that incremental models generally require use of the {{this}} template variable to identify new records.
-
-The `sql_where` field is supplied as a `where` condition on a subquery containing the model definition. This resultset is then inserted into the target model. This looks something like:
-
-```sql
-insert into schema.model (
-    select * from (
-        -- compiled model definition
-    ) where {{sql_where}}
-)
-```
-
-### 3. Feature: `materialized: ephemeral` https://github.com/analyst-collective/dbt/issues/78
-
-Ephemeral models are injected as CTEs (`with` statements) into any model that `ref`erences them. Ephemeral models are part of the dependency graph and generally function like any other model, except ephemeral models are not compiled to their own files or directly created in the database. This is useful for intermediary models which are shared by other downstream models, but shouldn't be queried directly from outside of dbt.
-
-To make a model ephemeral:
-
-```yml
-employees:
-    materialized: ephemeral
-```
-
-Suppose you wanted to exclude `employees` from your `users` table, but you don't want to clutter your analytics schema with an `employees` table.
-
-```sql
--- employees.sql
-select * from public.employees where is_deleted = false
-
--- users.sql
-select *
-from {{ref('users')}}
-where email not in (select email from {{ref('employees')}})
-```
-
-The compiled SQL would look something like:
-```sql
-with __dbt__CTE__employees as (
-  select * from public.employees where is_deleted = false
-)
-select *
-from users
-where email not in (select email from __dbt__CTE__employees)
-```
-
-Ephemeral models play nice with other ephemeral models, incremental models, and regular table/view models. Feel free to mix and match different materialization options to optimize for performance and simplicity.
-
-
-### 4. Feature: In-model configs https://github.com/analyst-collective/dbt/issues/88
-
-Configurations can now be specified directly inside of models. These in-model configs work exactly the same as configs inside of the dbt_project.yml file.
-
-An in-model-config looks like this:
-
-```sql
--- users.sql
-
--- python function syntax
-{{ config(materialized="incremental", sql_where="id > (select max(id) from {{this}})") }}
--- OR json syntax
-{{
-    config({"materialized:" "incremental", "sql_where" : "id > (select max(id) from {{this}})"})
-}}
-
-select * from public.users
-```
-
-The config resolution order is:
-  1. dbt_project.yml `model-defaults`
-  2. in-model config
-  3. dbt_project.yml `models` config
-
-### 5. Fix: dbt seed null values https://github.com/analyst-collective/dbt/issues/102
-
-Previously, `dbt seed` would insert empty CSV cells as `"None"`, whereas they should have been `NULL`. Not anymore!
-
-
----
-
-## dbt v0.3.0
-
-Version 0.3.0 comes with the following updates:
-
-#### 1. Parallel model creation https://github.com/analyst-collective/dbt/pull/83
-dbt will analyze the model dependency graph and can create models in parallel if possible. In practice, this can significantly speed up the amount of time it takes to complete `dbt run`. The number of threads dbt uses must be between 1 and 8. To configure the number of threads dbt uses, add the `threads` key to your dbt target in `~/.dbt/profiles.yml`, eg:
-
-```yml
-user:
-  outputs:
-    my-redshift:
-      type: redshift
-      threads: 4         # execute up to 4 models concurrently
-      host: localhost
-      ...
-  run-target: my-redshift
-```
-
-For a complete example, check out [a sample profiles.yml file](https://github.com/analyst-collective/dbt/blob/master/sample.profiles.yml)
-
-#### 2. Fail only within a single dependency chain https://github.com/analyst-collective/dbt/issues/63
-If a model cannot be created, it won't crash the entire `dbt run` process. The errant model will fail and all of its descendants will be "skipped". Other models which do not depend on the failing model (or its descendants) will still be created.
-
-#### 3. Logging https://github.com/analyst-collective/dbt/issues/64, https://github.com/analyst-collective/dbt/issues/65
-dbt will log output from the `dbt run` and `dbt test` commands to a configurable logging directory. By default, this directory is called `logs/`. The log filename is `dbt.log` and it is rotated on a daily basic. Logs are kept for 7 days.
-
-To change the name of the logging directory, add the following line to your `dbt_project.yml` file:
-```yml
-log-path: "my-logging-directory" # will write logs to my-logging-directory/dbt.log
-```
-
-#### 4. Minimize time models are unavailable in the database https://github.com/analyst-collective/dbt/issues/68
-Previously, dbt would create models by:
-1. dropping the existing model
-2. creating the new model
-
-This resulted in a significant amount of time in which the model was inaccessible to the outside world. Now, dbt creates models by:
-1. creating a temporary model `{model-name}__dbt_tmp`
-2. dropping the existing model
-3. renaming the tmp model name to the actual model name
-
-#### 5. Arbitrarily deep nesting https://github.com/analyst-collective/dbt/issues/50
-Previously, all models had to be located in a directory matching `models/{model group}/{model_name}.sql`. Now, these models can be nested arbitrarily deeply within a given dbt project. For instance, `models/snowplow/sessions/transformed/transformed_sessions.sql` is a totally valid model location with this release.
-
-To configure these deeply-nested models, just nest the config options within the `dbt_project.yml` file. The only caveat is that you need to specify the dbt project name as the first key under the `models` object, ie:
-
-```yml
-models:
-  'Your Project Name':
-    snowplow:
-      sessions:
-        transformed:
-          transformed_sessions:
-            enabled: true
-```
-
-More information is available on the [issue](https://github.com/analyst-collective/dbt/issues/50) and in the [sample dbt_project.yml file](https://github.com/analyst-collective/dbt/blob/master/sample.dbt_project.yml)
-
-#### 6. don't try to create a schema if it already exists https://github.com/analyst-collective/dbt/issues/66
-dbt run would execute `create schema if not exists {schema}`. This would fail if the dbt user didn't have sufficient permissions to create the schema, even if the schema already existed! Now, dbt checks for the schema existence and only attempts to create the schema if it doesn't already exist.
-
-#### 7. Semantic Versioning
-The previous release of dbt was v0.2.3.0 which isn't a semantic version. This and all future dbt releases will conform to semantic version in the format `{major}.{minor}.{patch}`.
----

-## dbt v0.2.3.0
-Version 0.2.3.0 of dbt comes with the following updates:
-
-#### 1. Fix: Flip referential integrity arguments (breaking)
-Referential integrity validations in a `schema.yml` file were previously defined relative to the *parent* table:
-```yaml
-account:
-  constraints:
-    relationships:
-      - {from: id, to: people, field: account_id}
-```
-
-Now, these validations are specified relative to the *child* table
-```yaml
-people:
-  constraints:
-    relationships:
-      - {from: account_id, to: accounts, field: id}
-```
-
-For more information, run `dbt test -h`
-
-#### 2. Feature: seed tables from a CSV
-Previously, auxiliary data needed to be shoehorned into a view comprised of union statements, eg.
-```sql
-select 22 as "type", 'Chat Transcript' as type_name, 'chatted via olark' as event_name union all
-select 21, 'Custom Redirect', 'clicked a custom redirect' union all
-select 6, 'Email', 'email sent' union all
-...
-```
-
-That's not a scalable solution. Now you can load CSV files into your data warehouse:
-1. Add a CSV file (with a header) to the `data/` directory
-2. Run `dbt seed` to create a table from the CSV file!
-3. The table name with be the filename (sans `.csv`) and it will be placed in your `run-target`'s schema
-
-Subsequent calls to `dbt seed` will truncate the seeded tables (if they exist) and re-insert the data. If the table schema changes, you can run `dbt seed --drop-existing` to drop the table and recreate it.
-
-For more information, run `dbt seed -h`
-
-#### 3. Feature: compile analytical queries
-
-Versioning your SQL models with dbt is a great practice, but did you know that you can also version your analyses? Any SQL files in the `analysis/` dir will be compiled (ie. table names will be interpolated) and placed in the `target/build-analysis/` directory. These analytical queries will _not_ be run against your data warehouse with `dbt run` -- you should copy/paste them into the data analysis tool of your choice.
-
-#### 4. Feature: accepted values validation
-
-In your `schema.yml` file, you can now add `accepted-values` validations:
-```yaml
-accounts:
-  constraints:
-    accepted-values:
-      - {field: type, values: ['paid', 'free']}
-```
-
-This test will determine how many records in the `accounts` model have a `type` other than `paid` or `free`.
-
-#### 5. Feature: switch profiles and targets on the command line
-
-Switch between profiles with `--profile [profile-name]` and switch between run-targets with `--target [target-name]`.
-
-Targets should be something like "prod" or "dev" and profiles should be something like "my-org" or "my-side-project"
-
-```yaml
-side-project:
-  outputs:
-    prod:
-      type: redshift
-      host: localhost
-      port: 5439
-      user: Drew
-      pass:
-      dbname: data_generator
-      schema: ac_drew
-    dev:
-      type: redshift
-      host: localhost
-      port: 5439
-      user: Drew
-      pass:
-      dbname: data_generator
-      schema: ac_drew_dev
-  run-target: dev
-```
-
-To compile models using the `dev` environment of my `side-project` profile:
-`$ dbt compile --profile side-project --target dev`
-or for `prod`:
-`$ dbt compile --profile side-project --target prod`
-
-You can also add a "profile' config to the `dbt_config.yml` file to fix a dbt project to a specific profile:
-
-```yaml
-...
-test-paths: ["test"]
-data-paths: ["data"]
-
-# Fix this project to the "side-project" profile
-# You can still use --target to switch between environments!
-profile: "side-project"
-
-model-defaults:
-....
-```

+# Contributing to `dbt-core`
+
+`dbt-core` is open source software. It is what it is today because community members have opened issues, provided feedback, and [contributed to the knowledge loop](https://www.getdbt.com/dbt-labs/values/). Whether you are a seasoned open source contributor or a first-time committer, we welcome and encourage you to contribute code, documentation, ideas, or problem statements to this project.
+
+1. [About this document](#about-this-document)
+2. [Getting the code](#getting-the-code)
+3. [Setting up an environment](#setting-up-an-environment)
+4. [Running `dbt` in development](#running-dbt-core-in-development)
+5. [Testing dbt-core](#testing)
+6. [Submitting a Pull Request](#submitting-a-pull-request)
+
+## About this document
+
+There are many ways to contribute to the ongoing development of `dbt-core`, such as by participating in discussions and issues. We encourage you to first read our higher-level document: ["Expectations for Open Source Contributors"](https://docs.getdbt.com/docs/contributing/oss-expectations).
+
+The rest of this document serves as a more granular guide for contributing code changes to `dbt-core` (this repository). It is not intended as a guide for using `dbt-core`, and some pieces assume a level of familiarity with Python development (virtualenvs, `pip`, etc). Specific code snippets in this guide assume you are using macOS or Linux and are comfortable with the command line.
+
+If you get stuck, we're happy to help! Drop us a line in the `#dbt-core-development` channel in the [dbt Community Slack](https://community.getdbt.com).
+
+### Notes
+
+- **Adapters:** Is your issue or proposed code change related to a specific [database adapter](https://docs.getdbt.com/docs/available-adapters)? If so, please open issues, PRs, and discussions in that adapter's repository instead. The sole exception is Postgres; the `dbt-postgres` plugin lives in this repository (`dbt-core`).
+- **CLA:** Please note that anyone contributing code to `dbt-core` must sign the [Contributor License Agreement](https://docs.getdbt.com/docs/contributor-license-agreements). If you are unable to sign the CLA, the `dbt-core` maintainers will unfortunately be unable to merge any of your Pull Requests. We welcome you to participate in discussions, open issues, and comment on existing ones.
+- **Branches:** All pull requests from community contributors should target the `main` branch (default). If the change is needed as a patch for a minor version of dbt that has already been released (or is already a release candidate), a maintainer will backport the changes in your PR to the relevant "latest" release branch (`1.0.latest`, `1.1.latest`, ...)
+
+## Getting the code
+
+### Installing git
+
+You will need `git` in order to download and modify the `dbt-core` source code. On macOS, the best way to download git is to just install [Xcode](https://developer.apple.com/support/xcode/).
+
+### External contributors
+
+If you are not a member of the `dbt-labs` GitHub organization, you can contribute to `dbt-core` by forking the `dbt-core` repository. For a detailed overview on forking, check out the [GitHub docs on forking](https://help.github.com/en/articles/fork-a-repo). In short, you will need to:
+
+1. Fork the `dbt-core` repository
+2. Clone your fork locally
+3. Check out a new branch for your proposed changes
+4. Push changes to your fork
+5. Open a pull request against `dbt-labs/dbt-core` from your forked repository
+
+### dbt Labs contributors
+
+If you are a member of the `dbt-labs` GitHub organization, you will have push access to the `dbt-core` repo. Rather than forking `dbt-core` to make your changes, just clone the repository, check out a new branch, and push directly to that branch.
+
+## Setting up an environment
+
+There are some tools that will be helpful to you in developing locally. While this is the list relevant for `dbt-core` development, many of these tools are used commonly across open-source python projects.
+
+### Tools
+
+These are the tools used in `dbt-core` development and testing:
+
+- [`tox`](https://tox.readthedocs.io/en/latest/) to manage virtualenvs across python versions. We currently target the latest patch releases for Python 3.7, 3.8, 3.9, and 3.10
+- [`pytest`](https://docs.pytest.org/en/latest/) to define, discover, and run tests
+- [`flake8`](https://flake8.pycqa.org/en/latest/) for code linting
+- [`black`](https://github.com/psf/black) for code formatting
+- [`mypy`](https://mypy.readthedocs.io/en/stable/) for static type checking
+- [`pre-commit`](https://pre-commit.com) to easily run those checks
+- [`changie`](https://changie.dev/) to create changelog entries, without merge conflicts
+- [`make`](https://users.cs.duke.edu/~ola/courses/programming/Makefiles/Makefiles.html) to run multiple setup or test steps in combination. Don't worry too much, nobody _really_ understands how `make` works, and our Makefile aims to be super simple.
+- [GitHub Actions](https://github.com/features/actions) for automating tests and checks, once a PR is pushed to the `dbt-core` repository
+
+A deep understanding of these tools in not required to effectively contribute to `dbt-core`, but we recommend checking out the attached documentation if you're interested in learning more about each one.
+
+#### Virtual environments
+
+We strongly recommend using virtual environments when developing code in `dbt-core`. We recommend creating this virtualenv
+in the root of the `dbt-core` repository. To create a new virtualenv, run:
+```sh
+python3 -m venv env
+source env/bin/activate
+```
+
+This will create and activate a new Python virtual environment.
+
+#### Docker and `docker-compose`
+
+Docker and `docker-compose` are both used in testing. Specific instructions for you OS can be found [here](https://docs.docker.com/get-docker/).
+
+
+#### Postgres (optional)
+
+For testing, and later in the examples in this document, you may want to have `psql` available so you can poke around in the database and see what happened. We recommend that you use [homebrew](https://brew.sh/) for that on macOS, and your package manager on Linux. You can install any version of the postgres client that you'd like. On macOS, with homebrew setup, you can run:
+
+```sh
+brew install postgresql
+```
+
+## Running `dbt-core` in development
+
+### Installation
+
+First make sure that you set up your `virtualenv` as described in [Setting up an environment](#setting-up-an-environment).  Also ensure you have the latest version of pip installed with `pip install --upgrade pip`. Next, install `dbt-core` (and its dependencies) with:
+
+```sh
+make dev
+# or
+pip install -r dev-requirements.txt -r editable-requirements.txt
+```
+
+When installed in this way, any changes you make to your local copy of the source code will be reflected immediately in your next `dbt` run.
+
+### Running `dbt-core`
+
+With your virtualenv activated, the `dbt` script should point back to the source code you've cloned on your machine. You can verify this by running `which dbt`. This command should show you a path to an executable in your virtualenv.
+
+Configure your [profile](https://docs.getdbt.com/docs/configure-your-profile) as necessary to connect to your target databases. It may be a good idea to add a new profile pointing to a local Postgres instance, or a specific test sandbox within your data warehouse if appropriate.
+
+## Testing
+
+Once you're able to manually test that your code change is working as expected, it's important to run existing automated tests, as well as adding some new ones. These tests will ensure that:
+- Your code changes do not unexpectedly break other established functionality
+- Your code changes can handle all known edge cases
+- The functionality you're adding will _keep_ working in the future
+
+Although `dbt-core` works with a number of different databases, you won't need to supply credentials for every one of these databases in your test environment. Instead, you can test most `dbt-core` code changes with Python and Postgres.
+
+### Initial setup
+
+Postgres offers the easiest way to test most `dbt-core` functionality today. They are the fastest to run, and the easiest to set up. To run the Postgres integration tests, you'll have to do one extra step of setting up the test database:
+
+```sh
+make setup-db
+```
+or, alternatively:
+```sh
+docker-compose up -d database
+PGHOST=localhost PGUSER=root PGPASSWORD=password PGDATABASE=postgres bash test/setup_db.sh
+```
+
+### Test commands
+
+There are a few methods for running tests locally.
+
+#### Makefile
+
+There are multiple targets in the Makefile to run common test suites and code
+checks, most notably:
+
+```sh
+# Runs unit tests with py38 and code checks in parallel.
+make test
+# Runs postgres integration tests with py38 in "fail fast" mode.
+make integration
+```
+> These make targets assume you have a local installation of a recent version of [`tox`](https://tox.readthedocs.io/en/latest/) for unit/integration testing and pre-commit for code quality checks,
+> unless you use choose a Docker container to run tests. Run `make help` for more info.
+
+Check out the other targets in the Makefile to see other commonly used test
+suites.
+
+#### `pre-commit`
+[`pre-commit`](https://pre-commit.com) takes care of running all code-checks for formatting and linting. Run `make dev` to install `pre-commit` in your local environment.  Once this is done you can use any of the linter-based make targets as well as a git pre-commit hook that will ensure proper formatting and linting.
+
+#### `tox`
+
+[`tox`](https://tox.readthedocs.io/en/latest/) takes care of managing virtualenvs and install dependencies in order to run tests. You can also run tests in parallel, for example, you can run unit tests for Python 3.7, Python 3.8, Python 3.9, and Python 3.10 checks in parallel with `tox -p`. Also, you can run unit tests for specific python versions with `tox -e py37`. The configuration for these tests in located in `tox.ini`.
+
+#### `pytest`
+
+Finally, you can also run a specific test or group of tests using [`pytest`](https://docs.pytest.org/en/latest/) directly. With a virtualenv active and dev dependencies installed you can do things like:
+
+```sh
+# run all unit tests in a file
+python3 -m pytest test/unit/test_graph.py
+# run a specific unit test
+python3 -m pytest test/unit/test_graph.py::GraphTest::test__dependency_list
+# run specific Postgres integration tests (old way)
+python3 -m pytest -m profile_postgres test/integration/074_postgres_unlogged_table_tests
+# run specific Postgres integration tests (new way)
+python3 -m pytest tests/functional/sources
+```
+
+> See [pytest usage docs](https://docs.pytest.org/en/6.2.x/usage.html) for an overview of useful command-line options.
+
+## Adding CHANGELOG Entry
+
+We use [changie](https://changie.dev) to generate `CHANGELOG` entries. **Note:** Do not edit the `CHANGELOG.md` directly. Your modifications will be lost.
+
+Follow the steps to [install `changie`](https://changie.dev/guide/installation/) for your system.
+
+Once changie is installed and your PR is created, simply run `changie new` and changie will walk you through the process of creating a changelog entry.  Commit the file that's created and your changelog entry is complete!
+
+You don't need to worry about which `dbt-core` version your change will go into. Just create the changelog entry with `changie`, and open your PR against the `main` branch. All merged changes will be included in the next minor version of `dbt-core`. The Core maintainers _may_ choose to "backport" specific changes in order to patch older minor versions. In that case, a maintainer will take care of that backport after merging your PR, before releasing the new version of `dbt-core`.
+
+## Submitting a Pull Request
+
+A `dbt-core` maintainer will review your PR. They may suggest code revision for style or clarity, or request that you add unit or integration test(s). These are good things! We believe that, with a little bit of help, anyone can contribute high-quality code.
+
+Automated tests run via GitHub Actions. If you're a first-time contributor, all tests (including code checks and unit tests) will require a maintainer to approve. Changes in the `dbt-core` repository trigger integration tests against Postgres. dbt Labs also provides CI environments in which to test changes to other adapters, triggered by PRs in those adapters' repositories, as well as periodic maintenance checks of each adapter in concert with the latest `dbt-core` code changes.
+
+Once all tests are passing and your PR has been approved, a `dbt-core` maintainer will merge your changes into the active development branch. And that's it! Happy developing :tada:

-dbt (data build tool) helps analysts write reliable, modular code using a workflow that closely mirrors software development.
+**[dbt](https://www.getdbt.com/)** enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications.

+## Understanding dbt
 
-### Testing
+Analysts using dbt can transform their data by simply writing select statements, while dbt handles turning these statements into tables and views in a data warehouse.

+These select statements, or "models", form a dbt project. Models frequently build on top of one another – dbt makes it easy to [manage relationships](https://docs.getdbt.com/docs/ref) between models, and [visualize these relationships](https://docs.getdbt.com/docs/documentation), as well as assure the quality of your transformations through [testing](https://docs.getdbt.com/docs/testing).
