Database Group Triage for week ending 2025-10-17
About
This issue is used by groupdatabase frameworks 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.
Process
-
Review any issues with undefined types -
Post any questions or pressing issues to the database group meeting doc

Review Top Queries for Changes
There were some new anomalous queries to review on the main database, broken down by metric type:
| Metric | # of queries |
|---|---|
| by_total_time | 0 |
| by_time_avg | 0 |
Please find the detailed query report here (Ops access required.)
For each query listed:
- Spend up to 30 minutes trying to understand its source.
- If needed, determine the team that owns the query and file an issue with them. A good place to start would be to check the relevant table's owner under
db/docs.
For additional context around how these queries were determined to be anomalous as well as historical rankings for known queries, all of the data we have collected lives in a database dump stored in artifacts in the query-stats-reporting repo on ops. Specifically check query-stats.yml for an example of how you can use this dump to locally rehydrate this database on your own Postgres instance and analyze the collected statistics. For this iteration of this report, queries are grouped by fingerprint.
Legacy query analysis
It is not necessary to look at this unless we need to check the new anomalous query report against the top query report on the main database.
Click to expand
For each database:
- Are there new queries in the top queries (See: K003 Top-15 Queries by total_time) compared to a previous report?
- If there are new queries, Spend up to 30 minutes trying to understand their sources
- 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
- 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
-
Review recent Primary Checkup for new Top Queries (K003) -
Review recent CI Checkup for new Top Queries (K003)
Review Dashboards on queries with large In-Lists
For both Sidekiq and Rails:
- If the report is empty, no action is needed
- For each item on the report:
- Determine what feature the query belongs to
- Create an issue for the team owning the feature category asking them to limit the maximum number of items in the in query
Int4 Saturation Review
For issue(s) linked below:
-
Ensure each table referenced in the report has an associated issue with ~"Gitlab.com Resource Saturation" and infradev attached
