Merge Request Process

Meltano uses an approval workflow for all merge requests.

  1. Create your merge request
  2. Assign the merge request to any eligible approvers as shown in the Gitlab MR UI (or specified in CODEOWNERS) for a review cycle
  3. Once the review is done the reviewer may approve the merge request or send it back for further iteration
  4. Once approved, the merge request can be merged by any Meltano maintainer

Reviews #

A contributor can ask for a review on any merge request, without this merge request being done and/or ready to merge.

Asking for a review is asking for feedback on the implementation, not approval of the merge request. It is also the perfect time to familiarize yourself with the code base. If you don’t understand why a certain code path would solve a particular problem, that should be sent as feedback: it most probably means the code is cryptic/complex or that the problem is bigger than anticipated.

Merge conflicts, failing tests and/or missing checkboxes should not be used as ground for sending back a merge request without feedback, unless specified by the reviewer.

Architectural Decision Records #

Meltano makes use of ADR’s (Architectural Decision Records) to record architectural decisions roughly as described by Michael Nygard. In a nutshell, these are used to document architectural decisions and to provide a record of the decisions made by the team and contributors in regard to Meltano’s architecture. These are held in docs/adr. To propose or add a new ADR, its simplest to create a new entry using adr-tools, and then send a long a merge request for review.

Changelog #

Meltano uses changelog-cli to populate the

Script #

Use changelog (new|change|fix|breaks) MESSAGE to describe your current work in progress.
