Infinispan WebSocket Server

The HTML 5 WebSocket Interface seems like a nice way of exposing an Infinispan Cache to web clients that are WebSocket enabled.

I just committed a first cut of the new Infinispan WebSocket Server to Subversion.

You get a very simple Cache object in your web page Javascript that supports:

1. put/get/remove operations on your Infinispan Cache.
2. notify/unnotify mechanism through which your web page can manage Cache entry update notifications, pushed to the browser.
   

Take a look at:

• the docs here.
• a short Screencast demo.

4.1.0. ALPHA3 is out

I've just cut Infinispan 4.1.0.ALPHA3, codenamed Radegast.  This release contains a number of fixes and bugs reported in 4.0.0 Starobrno as well as earlier alphas, and is quite likely to be the last alpha before a feature-complete 4.1.0.BETA1 is released.

A detailed changelog is available.  The release is downloadable in the usual place.

If you use Maven, please note, we now use the new JBoss Nexus-based Maven repository.  The Maven coordinates for Infinispan are still the same (groud id org.infinispan, artifact id infinispan-core, etc) but the repository you need to point to has changed.  Setting up your Maven settings.xml is described here.

Enjoy!

Boston, are you ready for Infinispan?

The JBoss World/Red Hat Summit organisers have asked me to put together a short note on what to expect at the conference with regards to Infinispan, and this has been published on the conference website.  I thought I'd share this with you as well.

http://summitblog.redhat.com/2010/04/12/boston-are-you-ready-for-infinispan/

In addition to the conference, this is also the first time JBoss is running JUDCon (JBoss Users and Developers Conference), a free event (limited on a first-come first-served basis) for the community, also in Boston.  Be sure to sign up as places are limited!

Look forward to seeing you there!

Infinispan 4.1Alpha2 is out!

We've just released Infinispan 4.1.0.Alpha2 with even more new functionality for the community to play with. Over the past few weeks we've been going backwards and forwards in the Infinispan development list discussing Infinispan's binary client server protocol called Hot Rod and in 4.1.0.Alpha2 we're proud to present the first versions of the Hot Rod server and java client implementations. Please visit this wiki to find out how to use Hot Rod's java client client and server. Please note that certain functionality such as clients receiving topology and hashing information has not yet been implemented.

Besides, Infinispan 4.1.0.Alpha2 is the first release to feature the new LIRS eviction policy and the new eviction design that batches updates, which in combination should provide users with more efficient and accurate eviction functionality.

Another cool feature added in this release is GridFileSystem: a new, experimental API that exposes an Infinispan-backed data grid as a file system. Specifically, the API works as an extension to the JDK's File, InputStream and OutputStream classes. You can read more on GridFileSystem here.

Finally, you can find the API docs for 4.1.0.Alpha2 here and again, please consider this an unstable release that is meant to gather feedback on the Hot Rod client/server modules and the new eviction design.

Cheers,
Galder & Mircea
