org.alfresco.repo.content.cleanup.EagerContentStoreCleaner
public class EagerContentStoreCleaner
This component is responsible cleaning up orphaned content.
Clean-up happens at two levels. Eager cleanup: (since 3.2) Ifeager cleanup is activated, then this
component listens to all content property change events and recorded for post-transaction
processing. All orphaned content is deleted from the registered store(s). Note that
any listeners are called as normal; backup or scrubbing
procedures should be plugged in as listeners if this is required.
Lazy cleanup:
This is triggered by means of a Quartz job. This is
a heavy-weight process that effectively compares the database metadata with the
content URLs controlled by the various stores. Once again, the listeners are called
appropriately.
How backup policies are affected:
When restoring the system from a backup, the type of restore required is dictated by
the cleanup policy being enforced. If eager cleanup is active, the system mustDeletedContentBackupCleanerListener, or
