Interested post over on the Terracotta blog (actual pdf available here) concerning performance between Terracotta’s caching mechanism and the JBoss TreeCache.

If you’re in a situation where scalability (and reliability) are a chief concern, you should definitely check the open source Terracotta offering out.

Even if you don’t necessarily live in a high-throughput environment, the paper does present an interesting argument towards moving clustering from the application to the JVM.

One of the problems we commonly face at work (w/ a thick client/j2ee server application) involves the synchronization of different client states and data (ClientA changes data, ClientB, ClientC, ClientD may need to know about it). I’ve yet to really work on a project that has required scalability to the extent that Terracotta (or even JBoss TreeCache) would provide but I have come to realize the significant performance problems associated with shipping (and responding to) high-volume synchronization messages across the wire.

Might just have to play a bit more with Terracotta during our next Hack Day.

If you’re attending JavaOne this year, there’s a couple Terracotta clustering clinics planned.
