[jboss-cluster-dev] Infinispan in JBoss AS

The topic of Infinispan integration into the AS has come up; seems like things are far enough along to start thinking about it. Let's assume for now that AS 6.0.0 will be out at toward the end of Q2 next year. Whether I mean Q2 calendar 2010 or Q2 Red Hat FY2011 is deliberately left vague. ;) Anyway, that date is just my rough impression, could be earlier, could be later. My wisdom and experience tells me not much earlier. :) I'll be very blunt and honest here. I love Infinispan; I want it in AS 6, but for Paul and I getting it in needs to be a lower priority than continuing working the long-standing cluster management/deployment issues. Where getting Infinispan in sits relative to Paul and I working on other general AS 6 goals (faster startup, better embedded support) I'll let Jason comment. The upshot of the above paragraph is I don't think it's right to count on a lot of cycles from Paul or I on this until probably after Christmas. And even then it needs to be maybe a 25-33% of our combined time thing. OK, I'm done shucking and jiving. ;) The big question is what to do about POJO Cache. Some options: 1) Infinispan comes up with the discussed JPA-style replacement. TBH, I think that's too big a task for the timeframes/resources involved. 2) We continue to use JBC/POJO Cache for FIELD granularity web session replication. I hate to say it but I think #2 probably makes more sense. The issue w/ #2 is how to manage both JBC and Infinispan instances. The AS has its own impl of the JBC CacheManager interface. It's actually a subinterface that exposes equivalent methods to CacheManager that return a POJO Cache. The AS and EJB3 code uses this subinterface, so for those we have a lot of freedom to change things. The Hibernate/JPA integrations w/ JBC and Infinispan use the JBC/Infinispan interfaces directly, and I don't want to change that in the AS. So, anyway, this is something we'd need to sort out, which doesn't seem like it would be that hard. The other big area is adapting from buddy replication to DIST. I think the big task there is just going to be testing. Rewrite white-box/gray-box tests that assume BR etc. -- Brian Stansberry Lead, AS Clustering JBoss by Red Hat
