Hi!
We deployed Metabase on Heroku last year, but since last week, Metabase is really unstable, becoming unavailable at least 3 times a day.
We only have 1 database connected (Snowflake).
Actions we already tried:
- Increase the Metabase memory from 2gb to 14gb.
- Sync Snowflake database only 1x per day, at 2AM.
- Increase the Snowflake auto-suspend time to 5 minutes
But the problem persists.
Important info: Heroku has 30 sec timeout by default, so, if a query/api call takes more than 30sec to execute, Heroku tries to cancel the request.
Question: This default 30s timeout from Heroku can prevent Metabase from operating normally?
