If you have a high number of alert instances, it can happen that the load on the database gets very high, as each state
transition of an alert instance is saved in the database.
This can be prevented by writing to the database periodically. For this the feature flag `alertingSaveStatePeriodic` needs
### Compressed alert state
When the `alertingSaveStateCompressed` feature toggle is enabled, Grafana saves the alert rule state in a compressed form, reducing database overhead for alerts with many instances.
### Save state periodically
High load can be also prevented by writing to the database periodically. For this the feature flag `alertingSaveStatePeriodic` needs
to be enabled. By default, it saves the states every 5 minutes to the database and on each shutdown. The periodic interval
can also be configured using the `state_periodic_save_interval` configuration flag. During this process, Grafana deletes all existing alert instances from the
database and then writes the entire current set of instances back in batches in a single transacton.
