Live db migrations and recovery #49036

merged 5 commits into from Apr 12, 2021

Commits on Apr 11, 2021

  1. Run database migrations in the background after started event 

    - Database migrations no longer block startup
- The migration is started shortly after the started event since they are cpu intensive and we do not want to compete with startup.
- Events are queued and processed when the migration is completed
- There is a safety to start discarding events if more than 10000 happen before migration is completed
- A notification is shown when the migration is in progress "The database is being upgraded. Integrations such as logbook and history that read the database may return inconsistent results until the migration completes."
- The database recovery logic can now recover at point after setup including purge, migration, and event insert. In short we can _always_ (hopefully) recover and start a new db  without a restart.
- The quick check is no longer performed on unclean shutdown since we can always recover live. The `db_integrity_check` option has been deprecated.
