Airbyte connectors QA checks

This document is listing all the static-analysis checks that are performed on the Airbyte connectors. These checks are running in our CI/CD pipeline and are used to ensure a connector is following the best practices and is respecting the Airbyte standards. Meeting these standards means that the connector will be able to be safely integrated into the Airbyte platform and released to registries (DockerHub, Pypi etc.). You can consider these checks as a set of guidelines to follow when developing a connector. They are by no mean replacing the need for a manual review of the connector codebase and the implementation of good test suites.

📄 Documentation​

Breaking changes must be accompanied by a migration guide​

Applies to the following connector types: source, destination Applies to the following connector languages: java, low-code, python, manifest-only Applies to connector with any support level Applies to connector with 100 internal support level Applies to connector with any Airbyte usage level

When a breaking change is introduced, we check that a migration guide is available. It should be stored under ./docs/integrations/<connector-type>s/<connector-name>-migrations.md. This document should contain a section for each breaking change, in order of the version descending. It must explain users which action to take to migrate to the new version.

Connectors must have user facing documentation​

Applies to the following connector types: source, destination Applies to the following connector languages: java, low-code, python, manifest-only Applies to connector with any support level Applies to connector with 100 internal support level Applies to connector with any Airbyte usage level

The user facing connector documentation should be stored under ./docs/integrations/<connector-type>s/<connector-name>.md.

Applies to the following connector types: source Applies to the following connector languages: python, low-code Applies to connector with any support level Applies to connector with 300 internal support level Applies to connector with any Airbyte usage level
