PLUS, LinkedIn open source Kafka and Lift moves beyond Scala!

Apache Cassandra Reaches 0.7

Version 0.7 of the Apache Cassandra distributed database is out now. In this release, large row support and secondary indexes have been added. The online schema now automates changes from the client API, which allows adding and modifying object definitions, without a cluster restart. Cassandra is deployed at organisations such as Digg, Facebook and Twitter.

LinkedIn Open Source New Distributed Message Queue

LinkedIn have announced they have open sourced the ‘Kafka‘ distributed message queue. This message queue allows various activity events generated on LinkedIn’s website to be tracked, for example keywords typed in a search query, or adverts presented.

“We feel that Kafka can be very useful in many places outside of LinkedIn. By open sourcing it, we hope to work with people in the community to keep improving Kafka in the future,” says Jun Rao, Principle Software Engineer at LinkedIn.

STS 2.5.2 Follows Spring Roo 1.1.1

SpringSource Tool Suite (STS) version 2.5.2 is out now with support for the recently-released Spring Roo 1.1.1. This new version features experimental agent-based reloading and integration with Spring User Agent Analysis. The graphical Spring Web Flow editor and the Spring and Groovy/Grails tooling, have also been improved.

Lift To Add JRuby Support

Lift 2.2 may have just been released, but David Pollack is already thinking ahead to the next release, and has decided that it’s time for the framework to move outside of Scala, after realising that “it’ll be 10+ years before the mainstream corporate developers (and they are the ones with money) adopt Scala.” Work is currently underway to make Lift work with JRuby. Pollack makes it clear that the move does not signal Lift abandoning Scala: “the core parts of Lift will always be written in Scala.” After JRuby support is added, Pollack intends to look at what languages Lift can support next: “Maybe it’ll be mainstream Java (if we can solve API issues like pattern matching in Ruby, maybe a better answer will come along for Java). Maybe it’ll be Clojure.” Watch this space!

The next release will be 4.0.0.CR,1 scheduled for release in early February.
