Infinispan based Hibernate Cache Provider available now!

Update (2009/11/13)! Infinispan 4.0.0.Beta2 based Hibernate second level cache provider now available in Hibernate 3.5 Beta2. However, neither Infinispan 4.0.0.Beta2 nor the Infinispan Cache Provider jar are available in the zip distribution. Instead, please download Infinispan 4.0.0.Beta2 from our download site and the Infinispan Cache Provider from our Maven repository.

I've just finished the development of an Infinispan 4.0 based Hibernate second level cache provider. This will be included from next Hibernate 3.5 release onwards but if you cannot wait and wanna play with it in the mean time, just checkout Hibernate trunk from our SVN repository and run 'mvn install'.

I've also written a wiki called "Using Infinispan as JPA/Hibernate Second Level Cache Provider" that should help users understand how to configure the Infinispan cache provider and how to make the most of it!

So, what's good about it? Why should I use it? First of all, since the cache provider is based on Infinispan, you benefit from all the improvements we've done to Infinispan in terms of performance and memory consumption so far and there are more to come!

On top of that, starting with this cache provider, we're aiming to reduce the number of files needed to modify in order to define the most commonly tweaked parameters. So, for example, by enabling eviction/expiration configuration on a per generic Hibernate data type or particular entity/collection type via hibernate.cfg.xml or persistence.xml, users don't have to touch to Infinispan's cache configuration file any more. You can find detailed information on how to do this in the "Using Infinispan as JPA/Hibernate Second Level Cache Provider" wiki

Please direct any feedback to the Infinispan user forum.



  1. I'll be trying this out in the next week or two. Our company's software product has been tested with a variety of hibernate second-level cache providers but we need a solution that allows partitioning to support massive cache + high availability; InfiniSpan is bleeding-edge for us but the feature set sounds perfect.

  2. Do you know if there is a way to make infinispan threads bein managed by websphere application server?

  3. Yes, all threads are accessed via executors and you can pass in an ExecutorFactory for any executor in the system. Using this interface you can pass in any threads you so wish. See ExecutorFactory.

  4. The option to tell Hibernate which caching implementation to use by specifying the name of a class that implements org.hibernate.cache.CacheProvider using the property hibernate.cache.provider_class. Hibernate is bundled with a number of built-in integrations with the open-source cache providers that are listed below. You can also implement your own and plug it in as outlined above.
