Purging data permanently removes information from the repository. Events derived from that data are purged with the data.

If you change the purge duration from a large timespan to a smaller one, the data is purged in increments of one hour, from oldest to newest, until the new data retention policy is met. This is done to reduce the load on the repository.

You can configure the data purge behavior in the following ways:
