## What changed? More granualar task queue stats tracking by priority level. ## Why? Preparation for https://github.com/temporalio/api/pull/611 where we intend to expose the priority-level stats to users. ## How did you test it? - [ ] built - [ ] run locally and tested manually - [x] covered by existing tests - [ ] added new unit test(s) - [ ] added new functional test(s) --------- Co-authored-by: David Reiss <[email protected]>
