[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3572) Create versioned entities groups

[Brian Cunningham (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40130#action_40130 ] 

Brian Cunningham commented on HHH-3572:
---------------------------------------

Has there been any progress with this issue?
I am using Hibernate Envers in a large reservation system that is being re-written based on a legacy system.
The old versioning mechanism effectively had 8 revision groups. If we had a similar option in Hibernate Envers it would make the migration much simpler.
Using one revision entity also means that the revision id will grow very large and could also become a source of a bottleneck.

> Each group would have its own versions table.
> This could speed up the system when there are a lot of versioned entities, as the versions tables would be less contested. However, if two versioned entities are connected by a (versioned) relation, they would have to be in the same group. So groups could minimally be strongly connected components of the relations graphs.
