Database Group Triage for week ending 2023-11-24

About

This issue is used by groupdatabase to triage issues and make sure they get properly assigned and prioritized. Each week, a bot will look up the old issue, pick the next assignee in the list, and submit a new issue with a list of any issues that may need attention from the team.

• Review any issues identified for triage

Issues needing triage (Labeled databasetriage)

For each issue below:

1. If the issue needs further investigation, spend up to 1 hour of investigating or fixing the issue.
2. If the issue is a typebug, assign it one of severity1, severity2, severity3, or severity4
3. Document any findings you make in a comment on the issue, and if the issue still needs additional work or refinement, consider looping in @alexives and @rogerwoo to help with scheduling and priority.
4. If the issue is incomplete, labeled ~"workflow::scheduled", and will take more than an hour to fix, remove databasetriage

Review Recent Postgres Checkup

For each database:

2. If there are new queries, Spend up to 30 minutes trying to understand their sources
3. If there are new queries, file an issue and assign to the team that owns the query, or if unable to source, then the team that owns the table
4. If there are no new queries, review the top 5 queries for each to see if there are already investigations, or file issues to investigate them
