ObjectGrid gets renamed to WebSphere eXtreme Scale

IBM relaunched XD today at the Impact conference in Vegas. ObjectGrid aka DataGrid will now be called "WebSphere eXtreme Scale" from a product point of view. As names go, it could be worse :) but I'll be shortening it to WXS in my slides as it's pretty long. I have two speaking sessions at Impact. The first is tomorrow at 16:45. This is about the new stuff over the past 12 months in ObjectGrid aka WXS and the second is on Wednesday at 10:30 with some of the ways customers are using it. Both sessions start with a gentle introduction to what the product does for the first 20 minutes and then gets in to the different topics of the sessions.

Can't we reduce the changes required for portability from ObjectGrid to Coherence or VISA VERSA by integrating the caching tool as a secondary level cache of hibernate?

Yes and thats an easy way to integrate eXtreme Scale or Coherence in to an application but Hibernate has a pretty poor L2 cache interface which is not efficient at all so you won't get best possible performance with that approach but it will absolutely give you a consistent clustered cache.

How come eXtreme Scale nor Coherence can participate in 2PC transactions? There has to be an architectural barrier to it.

For our project, it just makes the read-only use case the only one we can afford to have, because of no 2PC. Too expensive a tool, just for read-only, don't you think?
