For the alert groups query used by the `check_escalation_finished_task`, this resulted in a huge performance boost, taking the query time from 89mins to 4secs (on our largest production dataset). ## Which issue(s) this PR fixes closes #724 closes https://github.com/grafana/oncall-private/issues/1713 ## Checklist - [x] Unit, integration, and e2e (if applicable) tests updated - [x] Documentation added (or `pr:no public docs` PR label added if not required) - [x] `CHANGELOG.md` updated (or `pr:no changelog` PR label added if not required) |
