[hibernate-dev] RE: new SPI for EJB3/Seam

[Steve Ebersole]

LOL, this is essentially exactly what I proposed with the JBossCache
folks for efficient clustering.  One additional thing though that I
proposed was the ability to explicitly specify when to clear the
collected changeset and re-collecting.

Subject: new SPI for EJB3/Seam

For truly efficient clustering of extended persistence contexts in the
context of Seam or EJB3, we need a way to propagate unflushed
changesets. What we need is an SPI like this:

   Serializable changeset = session1.getChangeSet();

   session2.applyChangeSet(changeset);

where session2 is an empty session, or perhaps even a session with some
of the same entities as session1. The only state that needs to be sent
in the changeset is new entities, unflushed updates to entities and
deletions of entities.

Steve, WDYT?
