Xmas arrives early for Infinispan users! 5.0.0.ALPHA1 is out!

Just in time for Christmas, the first release in the 5.x series called 5.0.0.ALPHA1 is out. This release implements one of the most demanded features which is the ability to store non-Serializable objects into Infinispan data grids! You can now do so thanks to the ability to plug Infinispan with Externalizer implementations that know how to marshall/unmarshall a particular type. To find out more on how to implement this Externalizers and how to plug them, check the following article that explain this in great detail.

A very important benefit of using Infinispan’s Externalizer framework is that user classes now benefit from a lightning fast marshalling framework based on JBoss Marshalling. Back in the 4.0.0 days when we switched from JDK serialization to JBoss Marshalling, we saw a performance improvement of around 10-15% and we’re confident that 5.x user applications will see a similar performance increase once they start providing Externalizer implementations for their own types.

At this stage, it’s very important that Infinispan users have a go at implementing their own Externalizer implementations so that we have enough time to make adjustments based on feedback provided. Your input is crucial!!

Staying with the marshalling topic, another novelty included in this release is the ability to plug Hot Rod clients with portable serialization thanks to Apache Avro. This is not tremendously important right now, but once Hot Rod protocol clients have been written in other languages, they’d be able to seamlessly share data even if they’re written in different languages! In case you’re not aware, a Python Hot Rod client is already in the making…​

Finally, details of all issues fixed can be found here, the download is here, and please report issues here. :-)

Enjoy and Merry Christmas to all :)

Infinispan 4.2.0.CR2 "Ursus" is out!

Hi,

CR2 release fixes a critical issue from CR1: NumberFormatException when creating a new GlobalConfiguration objects (ISPN-797). Besides this, the client-server following two issues were fixed around client server modules:

  • In Memcached, negative items sizes in set/add should return CLIENT_ERROR (ISPN-784)

  • In REST, HEAD on nonexistent cache still produces status 500 (ISPN-795)

Big thanks to Galder for fixing these so quickly!

Cheers,

Mircea

Infinispan 4.2.0.CR1 "Ursus" is out!

Hi,

4.2.CR1 code name "Ursus" has just been released! It contains multiple fixes and improvements, mainly on memcached server and rehashing when cluster topology changes. The jgroups version was also upgraded to 2.11. Another thing that’s worth mentioning is that the default port for HotRod server has changed from 11311 to 11222 (here’s why).

You can download it from here. Please share your thoughts with us!

Cheers,

Mircea

BETA is out!!

I’ve just released the long-awaited first beta of Infinispan 4.2.0, codenamed Ursus.  The blocker that’s been keeping Ursus in Alpha for so long - ISPN-180 - is now complete and ready for you to take out for a spin.  Thanks to the work put in by Mircea and Vladimir, ISPN-180 adds support in the distribution algorithm to detect whether Infinispan instances are co-located on the same physical server (or even the same rack) and pick secondary owners of data with this knowledge in mind. This helps ensure maximum durability of data, so if physical machines - or even an entire rack - were to fail, data is not lost.  For more details on ISPN-180, have a look at this wiki page which details its use.

The JOPR/RHQ plugin now works in multi cache manager environments (ISPN-675) and thanks to ISPN-754, cache manager instances can be easily identified when using the JOPR/RHQ management GUI.  As a result of ISPN-754, JMX object names follow best practices as set up by Sun/Oracle and so this means that object names exported to JMX have changed from this version onwards. See this wiki page for detailed information.

For a list of all fixes since Alpha5, have a look at the release notes in JIRA, and as always, download the release here, and let us know what you think using the user forums.

Onward to release candidate and final release phases!  :-)

Enjoy, Manik

4.2.ALPHA1 "Ursus" is out!

Hi *,

4.2.ALPHA1 has just been released! Besides other things, it contains following two features: - supports deadlock detection for eagerly locking transactions (new) - an very interesting optimisation for eager locking, which allows one to benefit from eager locking semantics with the same performance as "lazy" locking. You can read more about this here. For download information go here. For a detailed list of features refer to the release notes.

Enjoy and please share your thoughts on our forums!

4.1.0.FINAL is out - and announcing 4.2.0

Yes, things have been quiet on this blog as of late, but a lot has been going on.  Let’s start with the big news.  After much work on feedback reported on the last Radegast release candidate, Infinispan 4.1.0.FINAL is finally ready.  Many thanks to the community who have worked tirelessly in testing stuff, reporting stuff.

This is a very important release.  If you are using 4.0.0 (Starobrno), I strongly recommend upgrading to Radegast as we have a whole host of big fixes, performance improvements and new features for you.  A full changelog is available on JIRA, but a few key features to note are server endpoints, a Java-based client for the Hot Rod protocol, and the new LIRS eviction algorithm.

Download it, give it a go, and talk about it on the forums.  Tell your friends about it, tweet about it.

The other interesting piece of news is the announcement of a 4.2.0 release.  We’ve decided to take a few key new features from 5.0.0 and release them earlier, as 4.2.0 - codenamed Ursus.  If you are interested in what’s going to be in Ursus, have a look at this feature set, and expect a beta on Ursus pretty soon now!

Enjoy! Manik

Radegast ever closer to a final release - CR3 is released.

As much as I expected 4.1.0.CR2 to be the last release candidate before a final release, we’ve decided to release another candidate for you to try out before pushing out a final release.  CR3 is now out and ready to roll.

There has been a lot of activity in the Infinispan community over the last 3 weeks, with lots of people putting CR2 through its paces, and reporting everything from the trivial through to the critical.  This is awesome stuff, folks - keep it up!

This release has fixed a whole bunch of things you guys have reported.  Many thanks to Galder, Mircea, Vladimir and Sanne, working hard around vacations to get this release out.

Detailed release note reports are on JIRA, and it can be downloaded in the usual place.  Use the forums and report stuff - push this as hard as you’ve been pushing CR2 and we will have that rock-solid final release we all want!

Enjoy! Manik
