The autoanalyze factor is set to 0.05 for the db, and we have not changed the default statistics target.
The CPU spike occurred between 13:05 - 13:15. last_autoanalyze for the table shows a time of 12:49; last_autovacuum does not show any activity around this time for any table. Checkpoint logs are also normal around this time. I'd like to understand if there are any other sources of activity I should be checking for that would account for the spike.
User workload is throttled to avoid excess load on the db, so a query is unlikely to have caused the spike. But we can dig deeper if other causes are ruled out.
Thanks
