  • I added CHANGELOG entry for this change.
  • Change is not relevant to the end user.

Changes

Prometheus recently introduced limit param in metadata APIs to allow users to opt for a limited number of results.

This PR implements the limit param in Thanos API.

Verification

  • Updated the unit tests to cover the case of when limit is passed.

I think we can omit the changelog here and add in the actual store implementation PR.
But not a big deal. We can update the changelog when you create another PR
