> Issue Type: Story
> Reporter: Todd Nine
> Assignee: David Johnson
>
> When the Core module EntityManager deletes or updates Entities in the
> Collections module, the Query Index records for the old versions of that
> Entity need to be deleted.
> To enable this, we added an eventing system to the Collections module so that
> callers can hook into entity create, update and delete events.
> And we added event handlers to clean up the Query Index records for those
> events.
> See the new package in Collections module:
> org.apache.usergrid.persistence.collection.event
> And in Core:
> org.apache.usergrid.corepersistence.events
