  • Ensure there is a link to an issue (except for internal cleanup and flaky test fixes), new features should have an RFC that documents use cases and test cases.

Tests

  • Bug fixes should have at least one unit or end-to-end test, enhancement and new features should have a sufficient number of tests.

Documentation

  • Apply the release notes (needs details) label if users need to know about this change.
  • New features should be documented.

  • There should be a comment at the top of each new or modified test to explain what the test does.

New flags

  • Is this flag really necessary?

If a workflow is added or modified:

Backward compatibility

  • Protobuf changes should be wire-compatible.
  • Changes to _vt tables and RPCs need to be backward compatible.

  • vtctl command output order should be stable and awk-able.

Since we are removing a flag, we need to update the website, right?

This will be done by doc-gen workflow.
For the Distributed Transaction section, we will do it as a separate task.

This is to keep the order of state such that if we order on the transaction state, the commit state comes on top.
