We had a similar problem upgrading from 21.2 to 21.3. The issue for us was that switching to 21.3 made Sentry query for events from errors_local
despite our consumers not writing to that Clickhouse table. We fixed this by:
- Upgrading to 21.4 from 21.3, which includes a migration to backfill
errors_local
fromsentry_local
- Switching
snuba-consumer
andsnuba-replacer
to write toerrors
rather thanevents
