High-five for Alpha5

image I’ve just released Infinispan 4.0.0.ALPHA5. Yes, I know you were expecting Beta1 already, but it is taking a little longer than anticipated. Anyway, Alpha5 has got some cool new stuff you’d definitely want to check out.

  • Migration scripts for EHCache

  • Internal performance improvements

  • Newer, faster JBoss Marshalling

As you know, your feedback is important to us, so please do download and try out what will hopefully be the last Alpha before we start releasing Betas.

A full changelog is on JIRA, and this release can be downloaded on our downloads page.

Cheers Manik

Blogger and syntax highlighting of code

If you happen to write a lot of tech articles on Blogger and frequently use code examples, it can be frustrating that Blogger has no built-in support for syntax highlighting. After some frustrating initial experiments with my own styles for code snippets, I found this excellent article:

http://abhisanoujam.blogspot.com/2008/12/blogger-syntax-highlighting.html In no time flat, I have converted all of my previous blog posts and they are now properly highlighted, complete with line numbers. :-) Lovely stuff.

Cheers Manik

Another alpha for Infinispan

imageYes, Infinispan 4.0.0.ALPHA4 is ready for a sound thrashing.

What’s new? Galder Zamarreño’s recent contribution of ripping out the marshalling framework Infinispan "inherited" from JBoss Cache and replacing it with JBoss Marshalling has made the marshalling code much leaner, more modular and more testable, and comes with a nifty performance boost too. What’s also interesting is that he has overcome issues with object stream caching (see my blog on the subject) by using JBoss Marshalling streams which can be reset. This too provides a very handy performance boost for short lived streams. (See ISPN-42, ISPN-84)

Mircea Markus has put together a bunch of migration scripts to migrate your JBoss Cache 3.x configuration to Infinispan. More migration scripts are on their way. (See ISPN-53, ISPN-54)

Vladimir Blagojevic has contributed the new lock() API - which allows for explicit, eager cluster-wide locks. (See ISPN-48)

Heiko Rupp has contributed the early days of a JOPR plugin, allowing Infinispan instances to be managed by JBoss AS 5.1.0’s embedded console as well as other environments. Read his guide to managing Infinispan with JOPR for more details.

And I’ve implemented some enhancements to the Future API. Now, rather than returning Futures, the xxxAsync() methods return a NotifyingFuture. NotifyingFuture extends Future, adding the ability to register a notifier such that the caller can be notified when the Future completes. Note that Future completion could mean any of successful completion, exception or cancellation, so the listener should check the state of the Future using get() on notification. For example:

NotifyingFuture<Void> f = cache.clearAsync().attachListener(new FutureListener<Void>() {
 public void futureDone(Future<Void> f) {
   if (f.get() && !f.isCancelled()) {
     System.out.println("clear operation succeeded");
   }
 }
});

The full change log for this release is available on JIRA. Download this release, and provide feedback on the Infinispan user forums.

Onward to Beta1!

Enjoy, Manik

Alpha3 ready to rumble!

So I’ve just tagged and cut Infinispan 4.0.0.ALPHA3. (Why are we starting with release 4.0.0? Read our FAQs!)

As I mentioned recently, I’ve implemented an uber-cool new asynchronous API for the cache and am dying to show it off/get some feedback on it. Yes, Alpha3 contains the async APIs. Why is this so important? Because it allows you to get the best of both worlds when it comes to synchronous and asynchronous network communications, and harnesses the parallelism and scalability you’d naturally expect from a halfway-decent data grid. And, as far as I know, we’re the first distributed cache - open or closed source - to offer such an API.

The release also contains other fixes, performance and stability improvements, and better javadocs throughout. One step closer to a full release.

Enjoy the release - available on our download page - and please do post feedback on the Infinispan User Forums.

Cheers Manik
