Infinispan 8.0.0.Beta3 out with Lucene 5, Functional API, Templates...etc

Infinispan querying has been upgraded to be usable with Lucene 5, with a lot of improvements particularly in terms of memory efficiency. With this upgrade, Lucene 4 support has been removed from the community project.

Configuration templates are finally here, meaning that users can now define cache configurations as template configurations, and then create cache configurations using those templates as base configuration.

A brand new, experimental, FunctionalMap API has been added that takes advantage of the lambda and async programming improvements introduced in Java 8. We consider this an advanced API that will enable Infinispan to grow beyond the well known javax.cache.Cache and java.util.concurrent.ConcurrentMap APIs. In the next few days I’ll be posting mutiple, detailed, blog posts looking at the different aspects of the API. If you area eager to get started, you can first have a look at a ConcurrentMap implementation using FunctionalMap to get a feel for it. Your feedback is highly appreciated!

Pedro has completed ISPN-2849 which should provide much better performance by liberating precious JGroups threads from having to wait for locks to be acquired remotely.
