* Alerting: Increase size of kvstore value type for MySQL to LONGTEXT alertmanager uses the kvstore to persist its notification log and the current column limit for MySQL (16.7mb) puts the maximum entries at a level that is potentially achievable for heavy alerting users (~40-80k entries). In comparison, the current type for PSQL (TEXT) is effectively unlimited and I believe SQLIte defaults to 2gb which is also plenty of leeway.
