+- Rollover `dbt.log` at 10 MB, and keep up to 5 backups, restoring previous behavior ([#4405](https://github.com/dbt-labs/dbt-core/pull/4405))
+- Use reference keys instead of full relation objects in cache events ([#4410](https://github.com/dbt-labs/dbt-core/pull/4410))

+- Relax version specifier for `dbt-extractor` to `~=0.4.0`, to support compiled wheels for additional architectures when available ([#4427](https://github.com/dbt-labs/dbt-core/pull/4427))
+
+## dbt-core 1.0.0rc3 (November 30, 2021)
+
+### Fixes
+- Support partial parsing of env_vars in metrics ([#4253](https://github.com/dbt-labs/dbt-core/issues/4293), [#4322](https://github.com/dbt-labs/dbt-core/pull/4322))
+- Fix typo in `UnparsedSourceDefinition.__post_serialize__` ([#3545](https://github.com/dbt-labs/dbt-core/issues/3545), [#4349](https://github.com/dbt-labs/dbt-core/pull/4349))
+
+### Under the hood
+- Change some CompilationExceptions to ParsingExceptions ([#4254](http://github.com/dbt-labs/dbt-core/issues/4254), [#4328](https://github.com/dbt-core/pull/4328))
+- Reorder logic for static parser sampling to speed up model parsing ([#4332](https://github.com/dbt-labs/dbt-core/pull/4332))
+- Use more augmented assignment statements ([#4315](https://github.com/dbt-labs/dbt-core/issues/4315)), ([#4311](https://github.com/dbt-labs/dbt-core/pull/4331))
+- Adjust logic when finding approximate matches for models and tests ([#3835](https://github.com/dbt-labs/dbt-core/issues/3835)), [#4076](https://github.com/dbt-labs/dbt-core/pull/4076))
+- Restore small previous behaviors for logging: JSON formatting for first few events; `WARN`-level stdout for `list` task; include tracking events in `dbt.log` ([#4341](https://github.com/dbt-labs/dbt-core/pull/4341))

+## dbt-core 1.0.0rc2 (November 22, 2021)
+
+### Breaking changes
+- Restrict secret env vars (prefixed `DBT_ENV_SECRET_`) to `profiles.yml` + `packages.yml` _only_. Raise an exception if a secret env var is used elsewhere ([#4310](https://github.com/dbt-labs/dbt-core/issues/4310), [#4311](https://github.com/dbt-labs/dbt-core/pull/4311))

+
+### Features
+- Avoid error when missing column in YAML description ([#4151](https://github.com/dbt-labs/dbt-core/issues/4151), [#4285](https://github.com/dbt-labs/dbt-core/pull/4285))

+
+## dbt-core 1.0.0rc1 (November 10, 2021)
+
+### Breaking changes
+- Replace `greedy` flag/property for test selection with `indirect_selection: eager/cautious` flag/property. Set to `eager` by default. **Note:** This reverts test selection to its pre-v0.20 behavior by default. `dbt test -s my_model` _will_ select multi-parent tests, such as `relationships`, that depend on unselected resources. To achieve the behavior change in v0.20 + v0.21, set `--indirect-selection=cautious` on the CLI or `indirect_selection: cautious` in yaml selectors. ([#4082](https://github.com/dbt-labs/dbt-core/issues/4082), [#4104](https://github.com/dbt-labs/dbt-core/pull/4104))
+- In v1.0.0, **`pip install dbt` will raise an explicit error.** Instead, please use `pip install dbt-<adapter>` (to use dbt with that database adapter), or `pip install dbt-core` (for core functionality). For parity with the previous behavior of `pip install dbt`, you can use: `pip install dbt-core dbt-postgres dbt-redshift dbt-snowflake dbt-bigquery` ([#4100](https://github.com/dbt-labs/dbt-core/issues/4100), [#4133](https://github.com/dbt-labs/dbt-core/pull/4133))
+- Reorganize the `global_project` (macros) into smaller files with clearer names. Remove unused global macros: `column_list`, `column_list_for_create_table`, `incremental_upsert` ([#4154](https://github.com/dbt-labs/dbt-core/pull/4154))
+- Introduce structured event interface, and begin conversion of all legacy logging ([#3359](https://github.com/dbt-labs/dbt-core/issues/3359), [#4055](https://github.com/dbt-labs/dbt-core/pull/4055))
+    - **This is a breaking change for adapter plugins, requiring a very simple migration.** See [`events` module README](core/dbt/events/README.md#adapter-maintainers) for details.
+    - If you maintain another kind of dbt-core plugin that makes heavy use of legacy logging, and you need time to cut over to the new event interface, you can re-enable the legacy logger via an environment variable shim, `DBT_ENABLE_LEGACY_LOGGER=True`. Be advised that we will remove this capability in a future version of dbt-core.
+
+### Features
+- Allow nullable `error_after` in source freshness ([#3874](https://github.com/dbt-labs/dbt-core/issues/3874), [#3955](https://github.com/dbt-labs/dbt-core/pull/3955))
+- Add `metrics` nodes ([#4071](https://github.com/dbt-labs/dbt-core/issues/4071), [#4235](https://github.com/dbt-labs/dbt-core/pull/4235))
+- Add support for `dbt init <project_name>`, and support for `skip_profile_setup` argument (`dbt init -s`) ([#4156](https://github.com/dbt-labs/dbt-core/issues/4156), [#4249](https://github.com/dbt-labs/dbt-core/pull/4249))
+
+### Fixes
+- Changes unit tests using `assertRaisesRegexp` to `assertRaisesRegex` ([#4136](https://github.com/dbt-labs/dbt-core/issues/4132), [#4136](https://github.com/dbt-labs/dbt-core/pull/4136))
+- Allow retries when the answer from a `dbt deps` is `None` ([#4178](https://github.com/dbt-labs/dbt-core/issues/4178), [#4225](https://github.com/dbt-labs/dbt-core/pull/4225))
+
+### Docs
+
+- Fix non-alphabetical sort of Source Tables in source overview page ([docs#81](https://github.com/dbt-labs/dbt-docs/issues/81), [docs#218](https://github.com/dbt-labs/dbt-docs/pull/218))
+- Add title tag to node elements in tree ([docs#202](https://github.com/dbt-labs/dbt-docs/issues/202), [docs#203](https://github.com/dbt-labs/dbt-docs/pull/203))
+- Account for test rename: `schema` &rarr; `generic`, `data` &rarr;` singular`. Use `test_metadata` instead of `schema`/`data` tags to differentiate ([docs#216](https://github.com/dbt-labs/dbt-docs/issues/216), [docs#222](https://github.com/dbt-labs/dbt-docs/pull/222))
+- Add `metrics` ([core#216](https://github.com/dbt-labs/dbt-core/issues/4235), [docs#223](https://github.com/dbt-labs/dbt-docs/pull/223))
+
+### Under the hood
+- Bump artifact schema versions for 1.0.0: manifest v4, run results v4, sources v3. Notable changes: added `metrics` nodes; schema test + data test nodes are renamed to generic test + singular test nodes; freshness threshold default values ([#4191](https://github.com/dbt-labs/dbt-core/pull/4191))
+- Speed up node selection by skipping `incorporate_indirect_nodes` if not needed ([#4213](https://github.com/dbt-labs/dbt-core/issues/4213), [#4214](https://github.com/dbt-labs/dbt-core/issues/4214))
+- When `on_schema_change` is set, pass common columns as `dest_columns` in incremental merge macros ([#4144](https://github.com/dbt-labs/dbt-core/issues/4144), [#4170](https://github.com/dbt-labs/dbt-core/pull/4170))
+- Clear adapters before registering in `lib` module config generation ([#4218](https://github.com/dbt-labs/dbt-core/pull/4218))
+- Remove official support for python 3.6, which is reaching end of life on December 23, 2021 ([#4134](https://github.com/dbt-labs/dbt-core/issues/4134), [#4223](https://github.com/dbt-labs/dbt-core/pull/4223))

+- Enable `on-run-start` and `on-run-end` hooks for `dbt test`. Add `flags.WHICH` to execution context, representing current task ([#3463](https://github.com/dbt-labs/dbt-core/issues/3463), [#4004](https://github.com/dbt-labs/dbt-core/pull/4004))
+
+### Features
+- Normalize global CLI arguments/flags ([#2990](https://github.com/dbt-labs/dbt/issues/2990), [#3839](https://github.com/dbt-labs/dbt/pull/3839))
+- Turns on the static parser by default and adds the flag `--no-static-parser` to disable it. ([#3377](https://github.com/dbt-labs/dbt/issues/3377), [#3939](https://github.com/dbt-labs/dbt/pull/3939))
+- Generic test FQNs have changed to include the relative path, resource, and column (if applicable) where they are defined. This makes it easier to configure them from the `tests` block in `dbt_project.yml` ([#3259](https://github.com/dbt-labs/dbt/pull/3259), [#3880](https://github.com/dbt-labs/dbt/pull/3880)
+- Turn on partial parsing by default ([#3867](https://github.com/dbt-labs/dbt/issues/3867), [#3989](https://github.com/dbt-labs/dbt/issues/3989))
+- Add `result:<status>` selectors to automatically rerun failed tests and erroneous models. This makes it easier to rerun failed dbt jobs with a simple selector flag instead of restarting from the beginning or manually running the dbt models in scope. ([#3859](https://github.com/dbt-labs/dbt/issues/3891), [#4017](https://github.com/dbt-labs/dbt/pull/4017))
+- `dbt init` is now interactive, generating profiles.yml when run inside existing project ([#3625](https://github.com/dbt-labs/dbt/pull/3625))
+
+### Under the hood
+
+- Fix intermittent errors in partial parsing tests ([#4060](https://github.com/dbt-labs/dbt-core/issues/4060), [#4068](https://github.com/dbt-labs/dbt-core/pull/4068))
+- Make finding disabled nodes more consistent ([#4069](https://github.com/dbt-labs/dbt-core/issues/4069), [#4073](https://github.com/dbt-labas/dbt-core/pull/4073))
+- Remove connection from `render_with_context` during parsing, thereby removing misleading log message ([#3137](https://github.com/dbt-labs/dbt-core/issues/3137), [#4062](https://github.com/dbt-labas/dbt-core/pull/4062))
+- Wait for postgres docker container to be ready in `setup_db.sh`. ([#3876](https://github.com/dbt-labs/dbt-core/issues/3876), [#3908](https://github.com/dbt-labs/dbt-core/pull/3908))
+- Prefer macros defined in the project over the ones in a package by default ([#4106](https://github.com/dbt-labs/dbt-core/issues/4106), [#4114](https://github.com/dbt-labs/dbt-core/pull/4114))
+- Dependency updates ([#4079](https://github.com/dbt-labs/dbt-core/pull/4079)), ([#3532](https://github.com/dbt-labs/dbt-core/pull/3532)
+- Schedule partial parsing for SQL files with env_var changes ([#3885](https://github.com/dbt-labs/dbt-core/issues/3885), [#4101](https://github.com/dbt-labs/dbt-core/pull/4101))
+- Schedule partial parsing for schema files with env_var changes ([#3885](https://github.com/dbt-labs/dbt-core/issues/3885), [#4162](https://github.com/dbt-labs/dbt-core/pull/4162))
+- Skip partial parsing when env_vars change in dbt_project or profile ([#3885](https://github.com/dbt-labs/dbt-core/issues/3885), [#4212](https://github.com/dbt-labs/dbt-core/pull/4212))

+## dbt-core 1.0.0b1 (October 11, 2021)
+
+### Breaking changes
+
+- The two type of test definitions are now "singular" and "generic" (instead of "data" and "schema", respectively). The `test_type:` selection method accepts `test_type:singular` and `test_type:generic`. (It will also accept `test_type:schema` and `test_type:data` for backwards compatibility) ([#3234](https://github.com/dbt-labs/dbt-core/issues/3234), [#3880](https://github.com/dbt-labs/dbt-core/pull/3880)). **Not backwards compatible:** The `--data` and `--schema` flags to `dbt test` are no longer supported, and tests no longer have the tags `'data'` and `'schema'` automatically applied.
+- Deprecated the use of the `packages` arg `adapter.dispatch` in favor of the `macro_namespace` arg. ([#3895](https://github.com/dbt-labs/dbt-core/issues/3895))
+
+### Features
+- Normalize global CLI arguments/flags ([#2990](https://github.com/dbt-labs/dbt-core/issues/2990), [#3839](https://github.com/dbt-labs/dbt-core/pull/3839))
+- Turns on the static parser by default and adds the flag `--no-static-parser` to disable it. ([#3377](https://github.com/dbt-labs/dbt-core/issues/3377), [#3939](https://github.com/dbt-labs/dbt-core/pull/3939))
+- Generic test FQNs have changed to include the relative path, resource, and column (if applicable) where they are defined. This makes it easier to configure them from the `tests` block in `dbt_project.yml` ([#3259](https://github.com/dbt-labs/dbt-core/pull/3259), [#3880](https://github.com/dbt-labs/dbt-core/pull/3880)
+- Turn on partial parsing by default ([#3867](https://github.com/dbt-labs/dbt-core/issues/3867), [#3989](https://github.com/dbt-labs/dbt-core/issues/3989))
+- Generic test can now be added under a `generic` subfolder in the `test-paths` directory. ([#4052](https://github.com/dbt-labs/dbt-core/pull/4052))
+
+### Fixes
+- Add generic tests defined on sources to the manifest once, not twice ([#3347](https://github.com/dbt-labs/dbt/issues/3347), [#3880](https://github.com/dbt-labs/dbt/pull/3880))
+- Skip partial parsing if certain macros have changed ([#3810](https://github.com/dbt-labs/dbt/issues/3810), [#3982](https://github.com/dbt-labs/dbt/pull/3892))
+- Enable cataloging of unlogged Postgres tables ([3961](https://github.com/dbt-labs/dbt/issues/3961), [#3993](https://github.com/dbt-labs/dbt/pull/3993))
+- Fix multiple disabled nodes ([#4013](https://github.com/dbt-labs/dbt/issues/4013), [#4018](https://github.com/dbt-labs/dbt/pull/4018))
+- Fix multiple partial parsing errors ([#3996](https://github.com/dbt-labs/dbt/issues/3006), [#4020](https://github.com/dbt-labs/dbt/pull/4018))
+- Return an error instead of a warning when runing with `--warn-error` and no models are selected ([#4006](https://github.com/dbt-labs/dbt/issues/4006), [#4019](https://github.com/dbt-labs/dbt/pull/4019))
+- Fixed bug with `error_if` test option ([#4070](https://github.com/dbt-labs/dbt-core/pull/4070))
+
+### Under the hood
+- Enact deprecation for `materialization-return` and replace deprecation warning with an exception. ([#3896](https://github.com/dbt-labs/dbt-core/issues/3896))
+- Build catalog for only relational, non-ephemeral nodes in the graph ([#3920](https://github.com/dbt-labs/dbt-core/issues/3920))
+- Enact deprecation to remove the `release` arg from the `execute_macro` method. ([#3900](https://github.com/dbt-labs/dbt-core/issues/3900))
+- Enact deprecation for default quoting to be True.  Override for the `dbt-snowflake` adapter so it stays `False`. ([#3898](https://github.com/dbt-labs/dbt-core/issues/3898))
+- Enact deprecation for object used as dictionaries when they should be dataclasses. Replace deprecation warning with an exception for the dunder methods of `__iter__` and `__len__` for all superclasses of FakeAPIObject. ([#3897](https://github.com/dbt-labs/dbt-core/issues/3897))
+- Enact deprecation for `adapter-macro` and replace deprecation warning with an exception. ([#3901](https://github.com/dbt-labs/dbt-core/issues/3901))
+- Add warning when trying to put a node under the wrong key.  ie. A seed under models in a `schema.yml` file. ([#3899](https://github.com/dbt-labs/dbt-core/issues/3899))
+- Plugins for `redshift`, `snowflake`, and `bigquery` have moved to separate repos: [`dbt-redshift`](https://github.com/dbt-labs/dbt-redshift), [`dbt-snowflake`](https://github.com/dbt-labs/dbt-snowflake), [`dbt-bigquery`](https://github.com/dbt-labs/dbt-bigquery)
+- Change the default dbt packages installation directory to `dbt_packages` from `dbt_modules`.  Also rename `module-path` to `packages-install-path` to allow default overrides of package install directory.  Deprecation warning added for projects using the old `dbt_modules` name without specifying a `packages-install-path`.  ([#3523](https://github.com/dbt-labs/dbt-core/issues/3523))
+- Update the default project paths to be `analysis-paths = ['analyses']` and `test-paths = ['tests]`. Also have starter project set `analysis-paths: ['analyses']` from now on.  ([#2659](https://github.com/dbt-labs/dbt-core/issues/2659))
+- Define the data type of `sources` as an array of arrays of string in the manifest artifacts. ([#3966](https://github.com/dbt-labs/dbt-core/issues/3966), [#3967](https://github.com/dbt-labs/dbt-core/pull/3967))
+- Marked `source-paths` and `data-paths` as deprecated keys in `dbt_project.yml` in favor of `model-paths` and `seed-paths` respectively.([#1607](https://github.com/dbt-labs/dbt-core/issues/1607))
+- Surface git errors to `stdout` when cloning dbt packages from Github. ([#3167](https://github.com/dbt-labs/dbt-core/issues/3167))

+# 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
+```
+
+#### 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
+```
+
+### 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.

+## Adding CHANGELOG Entry
+
+We use [changie](https://changie.dev) to generate `CHANGELOG` entries.  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!
+
 ## Submitting a Pull Request

 dbt Labs provides a CI environment to test changes to specific adapters, and periodic maintenance checks of `dbt-core` through Github Actions. For example, if you submit a pull request to the `dbt-redshift` repo, GitHub will trigger automated code checks and tests against Redshift.

@@ -6,7 +6,53 @@ The Events module is the implmentation for structured logging. These events repr
 The event module provides types that represent what is happening in dbt in `events.types`. These types are intended to represent an exhaustive list of all things happening within dbt that will need to be logged, streamed, or printed. To fire an event, `events.functions::fire_event` is the entry point to the module from everywhere in dbt.

 # Adding a New Event
-In `events.types` add a new class that represents the new event. This may be a simple class with no values, or it may be a dataclass with some values to construct downstream messaging. Only include the data necessary to construct this message within this class. You must extend all destinations (e.g. - if your log message belongs on the cli, extend `CliEventABC`) as well as the loglevel this event belongs to.
+In `events.types` add a new class that represents the new event. All events must be a dataclass with, at minimum, a code.  You may also include some other values to construct downstream messaging. Only include the data necessary to construct this message within this class. You must extend all destinations (e.g. - if your log message belongs on the cli, extend `Cli`) as well as the loglevel this event belongs to.  This system has been designed to take full advantage of mypy so running it will catch anything you may miss.
+
+## Required for Every Event
+
+- a string attribute `code`, that's unique across events
+- assign a log level by extending `DebugLevel`, `InfoLevel`, `WarnLevel`, or `ErrorLevel`
+- a message()
+- extend `File` and/or `Cli` based on where it should output
+
+Example
+```
+@dataclass
+class PartialParsingDeletedExposure(DebugLevel, Cli, File):
+    unique_id: str
+    code: str = "I049"
+
+    def message(self) -> str:
+        return f"Partial parsing: deleted exposure {self.unique_id}"
+
+```
+
+## Optional (based on your event)
+
+- Events associated with node status changes must have `report_node_data` passed in and be extended with `NodeInfo`
+- define `asdict` if your data is not serializable to json
+
+Example
+```
+@dataclass
+class SuperImportantNodeEvent(InfoLevel, File, NodeInfo):
+    node_name: str
+    run_result: RunResult
+    report_node_data: ParsedModelNode  # may vary
+    code: str = "Q036"
+
+    def message(self) -> str:
+        return f"{self.node_name} had overly verbose result of {run_result}"
+
+    @classmethod
+    def asdict(cls, data: list) -> dict:
+        return dict((k, str(v)) for k, v in data)
+
+```
+
+All values other than `code` and `report_node_data` will be included in the `data` node of the json log output.
+
+Once your event has been added, add a dummy call to your new event at the bottom of `types.py` and also add your new Event to the list `sample_values` in `test/unit/test_events.py'.

 # Performance Regression Testing
-This directory includes dbt project setups to test on and a test runner written in Rust which runs specific dbt commands on each of the projects. Orchestration is done via the GitHub Action workflow in `/.github/workflows/performance.yml`. The workflow is scheduled to run every night, but it can also be triggered manually.

-The github workflow hardcodes our baseline branch for performance metrics as `0.20.latest`. As future versions become faster, this branch will be updated to hold us to those new standards.
+## Attention!

-## Adding a new dbt project
-Just make a new directory under `performance/projects/`. It will automatically be picked up by the tests.
+PLEASE READ THIS README IN THE MAIN BRANCH
+The performance runner is always pulled from main regardless of the version being modeled or sampled. If you are not in the main branch, this information may be stale.

-## Adding a new dbt command
-In `runner/src/measure.rs::measure` add a metric to the `metrics` Vec. The Github Action will handle recompilation if you don't have the rust toolchain installed.
+## Description
+
+This test suite samples the performance characteristics of individual commits against performance models for prior releases. Performance is measured in project-command pairs which are assumed to conform to a normal distribution. The sampling and comparison is effecient enough to run against PRs.
+
+This collection of projects and commands should expand over time to reflect user feedback about poorly performing projects to protect against poor performance in these scenarios in future versions.
+
+Here are all the components of the testing module:
+
+- dbt project setups that are known performance bottlenecks which you can find in `/performance/projects/`, and a runner written in Rust that runs specific dbt commands on each of the projects.
+- Performance characteristics called "baselines" from released dbt versions in `/performance/baselines/`. Each branch will only have the baselines for its ancestors because when we compare samples, we compare against the lastest baseline available in the branch. 
+- A GitHub action for modeling the performance distribution for a new release: `/.github/workflows/model_performance.yml`.
+- A GitHub action for sampling performance of dbt at your commit and comparing it against a previous release: `/.github/workflows/sample_performance.yml`.
+
+At this time, the biggest risk in the design of this project is how to account for the natural variation of GitHub Action runs. Typically, performance work is done on dedicated hardware to elimiate this factor. However, there are ways to integrate the variation in obeservation tools if it can be measured.
+
+## Adding Test Scenarios
+
+A clear process for maintainers and community members to add new performance testing targets will exist after the next stage of the test suite is complete. For details, see #4768.
+
+## Investigating Regressions
+
+If your commit has failed one of the performance regression tests, it does not necessarily mean your commit has a performance regression. However, the observed runtime value was so much slower than the expected value that it was unlikely to be random noise. If it is not due to random noise, this commit contains the code that is causing this performance regression. However, it may not be the commit that introduced that code. That code may have been introduced in the commit before even if it passed due to natural variation in sampling. When investigating a performance regression, start with the failing commit and working your way backwards.
+
+Here's an example of how this could happen:
+
+```
+Commit
+A      <- last release
+B
+C      <- perf regression
+D
+E
+F      <- the first failing commit
+```
+- Commit A is measured to have an expected value for one performance metric of 30 seconds with a standard deviation of 0.5 seconds.
+- Commit B doesn't introduce a performance regression and passes the performance regression tests.
+- Commit C introduces a performance regression such that the new expected value of the metric is 32 seconds with a standard deviation still at 0.5 seconds, but we don't know this because we don't estimate the whole performance distribution on every commit because that is far too much work to run on every commit. It passes the performance regression test because we happened to sample a value of 31 seconds which is within our threshold for the original model. It's also only 2 standard deviations away from the actual performance model of commit C so even though it's not going to be a super common situation, it is expected to happen sometimes.
+- Commit D samples a value of 31.4 seconds and passes
+- Commit E samples a value of 31.2 seconds and passes
+- Commit F samples a value of 32.9 seconds and fails
+
+Because these performance regression tests are non-deterministic, it is frequently going to be possible to rerun the test on a failing commit and get it to pass. The more often we do this, the farther down the commit history we will be punting detection.
+
+If your PR is against `main` your commits will be compared against the latest baseline measurement found in `performance/baselines`. If this commit needs to be backported, that PR will be against the `.latest` branch and will also compare against the latest baseline measurement found in `performance/baselines` in that branch. These two versions may be the same or they may be different. For example, If the latest version of dbt is v1.99.0, the performance sample of your PR against main will compare against the baseline for v1.99.0. When those commits are backported to `1.98.latest` those commits will be compared against the baseline for v1.98.6 (or whatever the latest is at that time). Even if the compared baseline is the same, a different sample is taken for each PR. In this case, even though it should be rare, it is possible for a performance regression to be detected in one of the two PRs even with the same baseline due to variation in sampling.
+
+## The Statistics
+Particle physicists need to be confident in declaring new discoveries, snack manufacturers need to be sure each individual item is within the regulated margin of error for nutrition facts, and weight-rated climbing gear needs to be produced so you can trust your life to every unit that comes off the line. All of these use cases use the same kind of math to meet their needs: sigma-based p-values. This section will peel apart that math with the help of a physicist and walk through how we apply this approach to performance regression testing in this test suite.
+
+You are likely familiar with forming a hypothesis of the form "A and B are correlated" which is known as _the research hypothesis_. Additionally, it follows that the hypothesis "A and B are not correlated" is relevant and is known as _the null hypothesis_. When looking at data, we commonly use a _p-value_ to determine the significance of the data. Formally, a _p-value_ is the probability of obtaining data at least as extreme as the ones observed, if the null hypothesis is true. To refine this definition, The experimental partical physicist [Dr. Tommaso Dorigo](https://userswww.pd.infn.it/~dorigo/#about) has an excellent [glossary](https://www.science20.com/quantum_diaries_survivor/fundamental_glossary_higgs_broadcast-85365) of these terms that helps clarify: "'Extreme' is quite tricky instead: it depends on what is your 'alternate hypothesis' of reference, and what kind of departure it would produce on the studied statistic derived from the data. So 'extreme' will mean 'departing from the typical values expected for the null hypothesis, toward the values expected from the alternate hypothesis.'" In the context of performance regression testing, our research hypothesis is that "after commit A, the codebase includes a performance regression" which means we expect the runtime of our measured processes to be _slower_, not faster than the expected value.
+
+Given this definition of p-value, we need to explicitly call out the common tendancy to apply _probability inversion_ to our observations. To quote [Dr. Tommaso Dorigo](https://www.science20.com/quantum_diaries_survivor/fundamental_glossary_higgs_broadcast-85365) again, "If your ability on the long jump puts you in the 99.99% percentile, that does not mean that you are a kangaroo, and neither can one infer that the probability that you belong to the human race is 0.01%." Using our previously defined terms, the p-value is _not_ the probability that the null hypothesis _is true_.
+
+This brings us to calculating sigma values. Sigma refers to the standard deviation of a statistical model, which is used as a measurement of how far away an observed value is from the expected value. When we say that we have a "3 sigma result" we are saying that if the null hypothesis is true, this is a particularly unlikely observation—not that the null hypothesis is false. Exactly how unlikely depends on what the expected values from our research hypothesis are. In the context of performance regression testing, if the null hypothesis is false, we are expecting the results to be _slower_ than the expected value not _slower or faster_. Looking at a normal distrubiton below, we can see that we only care about one _half_ of the distribution: the half where the values are slower than the expected value. This means that when we're calculating the p-value we are not including both sides of the normal distribution.
+
+![normal distibution](./images/normal.svg)
+
+Because of this, the following table describes the significance of each sigma level for our _one-sided_ hypothesis:
+
+| σ   | p-value        | scientific significance |
+| --- | -------------- | ----------------------- |
+| 1 σ | 1 in 6         |                         |
+| 2 σ | 1 in 44        |                         |
+| 3 σ | 1 in 741       |  evidence               |
+| 4 σ | 1 in 31,574    |                         |
+| 5 σ | 1 in 3,486,914 |  discovery              |
+
+When detecting performance regressions that trigger alerts, block PRs, or delay releases we want to be conservative enough that detections are infrequently triggered by noise, but not so conservative as to miss most actual regressions. This test suite uses a 3 sigma standard so that only about 1 in every 700 runs is expected to fail the performance regression test suite due to expected variance in our measurements.
+
+In practice, the number of performance regression failures due to random noise will be higher because we are not incorporating the variance of the tools we use to measure, namely GHA.
+
+### Concrete Example: Performance Regression Detection
+
+The following example data was collected by running the code in this repository in Github Actions.
+
+In dbt v1.0.3, we have the following mean and standard deviation when parsing a dbt project with 2000 models:
+
+μ (mean):   41.22<br/>
+σ (stddev): 0.2525<br/>
+
+The 2-sided 3 sigma range can be calculated with these two values via:
+
+x < μ - 3 σ or x > μ + 3 σ<br/>
+x < 41.22 - 3 * 0.2525 or x > 41.22 + 3 * 0.2525 <br/>
+x < 40.46 or x > 41.98<br/>
+
+It follows that the 1-sided 3 sigma range for performance regressions is just:<br/>
+x > 41.98
+
+If when we sample a single `dbt parse` of the same project with a commit slated to go into dbt v1.0.4, we observe a 42s parse time, then this observation is so unlikely if there were no code-induced performance regressions, that we should investigate if there is a performance regression in any of the commits between this failure and the commit where the initial distribution was measured.
+
+Observations with 3 sigma significance that are _not_ performance regressions could be due to observing unlikely values (roughly 1 in every 750 observations), or variations in the instruments we use to take these measurements such as github actions. At this time we do not measure the variation in the instruments we use to account for these in our calculations which means failures due to random noise are more likely than they would be if we did take them into account.
+
+### Concrete Example: Performance Modeling
+
+Once a new dbt version is released (excluding pre-releases), the performance characteristics of that released version need to be measured. In this repository this measurement is referred to as a baseline.
+
+After dbt v1.0.99 is released, a github action running from `main`, for the latest version of that action, takes the following steps:
+- Checks out main for the latest performance runner
+- pip installs dbt v1.0.99
+- builds the runner if it's not already in the github actions cache
+- uses the performance runner model sub command with `./runner model`.
+- The model subcommand calls hyperfine to run all of the project-command pairs a large number of times (maybe 20 or so) and save the hyperfine outputs to files in `performance/baselines/1.0.99/` one file per command-project pair.
+- The action opens two PRs with these files: one against `main` and one against `1.0.latest` so that future PRs against these branches will detect regressions against the performance characteristics of dbt v1.0.99 instead of v1.0.98.
+- The release driver for dbt v1.0.99 reviews and merges these PRs which is the sole deliverable of the performance modeling work.

 ## Future work
- add more projects to test different configurations that have been known bottlenecks
- add more dbt commands to measure
- possibly using the uploaded json artifacts to store these results so they can be graphed over time
- reading new metrics from a file so no one has to edit rust source to add them to the suite
- instead of building the rust every time, we could publish and pull down the latest version.
- instead of manually setting the baseline version of dbt to test, pull down the latest stable version as the baseline.
+- pin commands to projects by reading commands from a file defined in the project.
+- add a postgres warehouse to run `dbt compile` and `dbt run` commands
+- add more projects to test different configurations that have been known performance bottlenecks
+- Account for github action variation: Either measure it, or eliminate it. To measure it we could set up another action that periodically samples the same version of dbt and use a 7 day rolling variation. To eliminate it we could run the action using something like [act](https://github.com/nektos/act) on dedicated hardware.
+- build in a git-bisect run to automatically identify the commits that caused a performance regression by modeling each commit's expected value for the failing metric. Running this automatically, or even providing a script to do this locally would be useful.
