+# **what?**
+# On push, if anything in core/dbt/docs or core/dbt/cli has been
+# created or modified, regenerate the CLI API docs using sphinx.
+
+# **why?**
+# We watch for changes in core/dbt/cli because the CLI API docs rely on click
+# and all supporting flags/params to be generated. We watch for changes in
+# core/dbt/docs since any changes to sphinx configuration or any of the
+# .rst files there could result in a differently build final index.html file.
+
+# **when?**
+# Whenever a change has been pushed to a branch, and only if there is a diff
+# between the PR branch and main's core/dbt/cli and or core/dbt/docs dirs.
+
+# TODO: add bot comment to PR informing contributor that the docs have been committed

-# **what?**
-# This workflow models the performance characteristics of a point in time in dbt.
-# It runs specific dbt commands on committed projects multiple times to create and
-# commit information about the distribution to the current branch. For more information
-# see the readme in the performance module at /performance/README.md.
-#
-# **why?**
-# When developing new features, we can take quick performance samples and compare
-# them against the commited baseline measurements produced by this workflow to detect
-# some performance regressions at development time before they reach users.
-#
-# **when?**
-# This is only run once directly after each release (for non-prereleases). If for some
-# reason the results of a run are not satisfactory, it can also be triggered manually.

 # **what?**
-# Release workflow provides the following steps:
-# - checkout the given commit;
-# - validate version in sources and changelog file for given version;
-# - bump the version and generate a changelog if needed;
-# - merge all changes to the target branch if needed;
-# - run unit and integration tests against given commit;
-# - build and package that SHA;
-# - release it to GitHub and PyPI with that specific build;
-# - release it to Docker
-#
+# Take the given commit, run unit tests specifically on that sha, build and
+# package it, and then release to GitHub and PyPi with that specific build
+
 # **why?**
 # Ensure an automated and tested release process
-#
-# **when?**
-# This workflow can be run manually on demand or can be called by other workflows

 The "tasks" map to top-level dbt commands.

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.

+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.

+- **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`, ...). If an issue fix applies to a release branch, that fix should be first committed to the development branch and then to the release branch (rarely release-branch fixes may not apply to `main`).
-- **Releases**: Before releasing a new minor version of Core, we prepare a series of alphas and release candidates to allow users (especially employees of dbt Labs!) to test the new version in live environments. This is an important quality assurance step, as it exposes the new code to a wide variety of complicated deployments and can surface bugs before official release. Releases are accessible via our [supported installation methods](https://docs.getdbt.com/docs/core/installation-overview#install-dbt-core).

-Code can be merged into the current development branch `main` by opening a pull request. If the proposal looks like it's on the right track, then a `dbt-core` maintainer will triage the PR and label it as `ready_for_review`. From this point, two code reviewers will be assigned with the aim of responding to any updates to the PR within about one week. 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. Once merged, your contribution will be available for the next release of `dbt-core`.

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:

The base class scaffolds out methods that every adapter project usually should implement for smooth communication between dbt and database.

-# dbt/artifacts
-
-## Overview
-This directory is meant to be a lightweight module that is independent (and upstream of) the rest of `dbt-core` internals.
-
-Its primary responsibility is to define simple data classes that represent the versioned artifact schemas that dbt writes as JSON files throughout execution. 
-
-Eventually, this module may be released as a standalone package (e.g. `dbt-artifacts`) to support stable programmatic parsing of dbt artifacts.
-
-`dbt/artifacts` is organized into artifact 'schemas' and 'resources'. Schemas represent the final serialized artifact objects, while resources represent smaller components within those schemas.
-
-### dbt/artifacts/schemas
-
-Each major version of a schema under `dbt/artifacts/schema` is defined in its corresponding `dbt/artifacts/schema/<artifact-name>/v<version>` directory. Before `dbt/artifacts` artifact schemas were always modified in-place, which is why older artifacts are those missing class definitions.
-
-Currently, there are four artifact schemas defined in `dbt/artifact/schemas`:
-
-| Artifact name | File             | Class                            | Latest definition                 |
-|---------------|------------------|----------------------------------|-----------------------------------|
-| manifest      | manifest.json    | WritableManifest                 | dbt/artifacts/schema/manifest/v12 |
-| catalog       | catalog.json     | CatalogArtifact                  | dbt/artifacts/schema/catalog/v1   |
-| run           | run_results.json | RunResultsArtifact               | dbt/artifacts/schema/run/v5       |
-| freshness     | sources.json     | FreshnessExecutionResultArtifact | dbt/artifacts/schema/freshness/v3 |
-
-
-### dbt/artifacts/resources
-
-All existing resources are defined under `dbt/artifacts/resources/v1`.
-
-## Making changes to dbt/artifacts
-
-### All changes
-
-All changes to any fields will require a manual update to [dbt-jsonschema](https://github.com/dbt-labs/dbt-jsonschema) to ensure live checking continues to work.
-
-### Non-breaking changes
-
-Freely make incremental, non-breaking changes in-place to the latest major version of any artifact (minor or patch bumps). The only changes that are fully forward and backward compatible are:
-* Adding a new field with a default
-* Deleting a field with a default. This is compatible in terms of serialization and deserialization, but still may be lead to suprising behaviour:
-    * For artifact consumers relying on the fields existence (e.g. `manifest["deleted_field"]` will stop working unless the access was implemented safely)
-    * Old code (e.g. in dbt-core) that relies on the value of the deleted field may have surprising behaviour given only the default value will be set when instantiated from the new schema
-
-These types of minor, non-breaking changes are tested by [tests/unit/artifacts/test_base_resource.py::TestMinorSchemaChange](https://github.com/dbt-labs/dbt-core/blob/main/tests/unit/artifacts/test_base_resource.py).
-
-
-#### Updating [schemas.getdbt.com](https://schemas.getdbt.com)
-Non-breaking changes to artifact schemas require an update to the corresponding jsonschemas published to [schemas.getdbt.com](https://schemas.getdbt.com), which are defined in https://github.com/dbt-labs/schemas.getdbt.com. To do so: 
-Note this must be done AFTER the core pull request is merged, otherwise we may end up with unresolvable conflicts and schemas that are invalid prior to base pull request merge. You may create the schemas.getdbt.com pull request prior to merging the base pull request, but do not merge until afterward.
-1. Create a PR in https://github.com/dbt-labs/schemas.getdbt.com which reflects the schema changes to the artifact. The schema can be updated in-place for non-breaking changes. Example PR: https://github.com/dbt-labs/schemas.getdbt.com/pull/39
-2. Merge the https://github.com/dbt-labs/schemas.getdbt.com PR
-
-Note: Although `jsonschema` validation using the schemas in [schemas.getdbt.com](https://schemas.getdbt.com) is not encouraged or formally supported, `jsonschema` validation should still continue to work once the schemas are updated because they are forward-compatible and can therefore be used to validate previous minor versions of the schema.
-
-### Breaking changes
-A breaking change is anything that:
-* Deletes a required field
-* Changes the name or type of an existing field
-* Removes the default value of an existing field
-
-These should be avoided however possible. When necessary, multiple breaking changes should be bundled together, to aim for minimal disruption across the ecosystem of tools that leverage dbt metadata. 
-
-When it comes time to make breaking changes, a new versioned artifact should be created as follows: 
- 1. Create a new version directory and file that defines the new artifact schema under `dbt/artifacts/schemas/<artifact>/v<next-artifact-version>/<artifact>.py`
- 2. If any resources are having breaking changes introduced, create a new resource class that defines the new resource schema under `dbt/artifacts/resources/v<next-resource-version>/<resource>.py`
- 3. Implement upgrade paths on the new versioned artifact class so it can be constructed given a dictionary representation of any previous version of the same artifact
-     * TODO: link example once available
-4. Implement downgrade paths on all previous versions of the artifact class so they can still be constructed given a dictionary representation of the new artifact schema
-    * TODO: link example once available
-5. Update the 'latest' aliases to point to the new version of the artifact and/or resource:
-    * Artifact: `dbt/artifacts/schemas/<artifact>/__init__.py `
-    * Resource: `dbt/artifacts/resources/__init__.py `
-
-Downstream consumers (e.g. `dbt-core`) importing from the latest alias are susceptible to breaking changes. Ideally, any incompatibilities should be caught my static type checking in those systems. However, it is always possible for consumers to pin imports to previous versions via `dbt.artifacts.schemas.<artifact>.v<prev-version>`.

-        The presence of a setting for `store_failures_as` overrides any existing setting for `store_failures`,
-        regardless of level of granularity. If `store_failures_as` is not set, then `store_failures` takes effect.
-        At the time of implementation, `store_failures = True` would always create a table; the user could not
-        configure this. Hence, if `store_failures = True` and `store_failures_as` is not specified, then it
-        should be set to "table" to mimic the existing functionality.
-
-        A side effect of this overriding functionality is that `store_failures_as="view"` at the project
-        level cannot be turned off at the model level without setting both `store_failures_as` and
-        `store_failures`. The former would cascade down and override `store_failures=False`. The proposal
-        is to include "ephemeral" as a value for `store_failures_as`, which effectively sets
-        `store_failures=False`.
-
-        The exception handling for this is tricky. If we raise an exception here, the entire run fails at
-        parse time. We would rather well-formed models run successfully, leaving only exceptions to be rerun
-        if necessary. Hence, the exception needs to be raised in the test materialization. In order to do so,
-        we need to make sure that we go down the `store_failures = True` route with the invalid setting for
-        `store_failures_as`. This results in the `.get()` defaulted to `True` below, instead of a normal
-        dictionary lookup as is done in the `if` block. Refer to the test materialization for the
-        exception that is raise as a result of an invalid value.
-
-        The intention of this block is to behave as if `store_failures_as` is the only setting,
-        but still allow for backwards compatibility for `store_failures`.
