Dear Infinispan community,


We're pleased to announce the final release of Infinispan 6.0 "Infinium". As announced, this is the first Infinispan stable version to be released under the terms of Apache License v2.0.


This release brings some highly demanded features besides many stability enhancements and bug fixes:


  • Support for remote query. It is now possible for the HotRod clients to query an Infinispan grid using a new expressive query DSL. This querying functionality is built on top of Apache Lucene and Google Protobuf and lays the foundation for storing information and querying an Infinispan server in a language neutral manner. The Java HotRod client has already been enhanced to support this, the soon-to-be announced C++ HotRod client will also contain this functionality (initially for write/read, then full blown querying).
  • C++ HotRod client.  Allows C++ applications to read and write information from an Infinispan server. This is a fully fledged HotRod client that is topology (level 2) and consistent hash aware (level 3) and will be released in the following days. Some features (such as Remote Query and SSL support) will be developed during the next iteration so that it maintains feature parity with its Java counterpart.
  • Better persistence integration. We’ve revisited the entire cache loader API and we’re quite pleased with the result: the new Persistence API brought by Infinispan 6.0 supports parallel iteration of the stored entries, reduces the overall serialization overhead and also is aligned with the JSR-107 specification, which makes implementations more portable.
  • A more efficient FileCacheStore implementation. This file store is built with efficiency in mind: it outperforms the existing file store with up to 2 levels of magnitude. This comes at a cost though, as keys need to be kept  in memory. Thanks to Karsten Blees for contributing this!
  • Support for heterogeneous clusters. Up to this release, every member of the cluster owns an equal share of the cluster’s data. This doesn’t work well if one machine is more powerful than the other cluster participants. This functionality allows specifying the amount of data, compared with the average, held by a particular machine.
  • A new set of usage and performance statistics developed within the scope of the CloudTM project.
  • JCache (JSR-107) implementation upgrade. First released in Infinispan 5.3.0, the standard caching support is now upgraded to version 1.0.0-PFD.


For a complete list of features included in this release please refer to the release notes.
The user documentation for this release has been revamped and migrated to the new website - we think it looks much better and hope you’ll like it too!
This release has spread over a period of 5 months: a sustained effort from the core development team, QE team and our growing community - a BIG thanks to everybody involved!

Cheers,
Adrian
