@kainzje this was a question regarding Grafana backend database and not timeseries database.
@svetb sqlite usually works up until a certain load (number of users, alert rules). But with a lot of users or alert rules then we recommend MySQL/Postgres, Lately I’ve also seen more and more people running sqlite on docker with NFS backed volumes which is a bad idea and leads to a lot of locks. If you think you will get more and more users/alert rules over time and/or think you’ll need HA in the future I would recommend switching now.
