At this moment, I have in my mailbox two messages of the vibrant Apache Software Foundation Announcements’s Mailing List and of the Apache Cassandra’s Users list
.
Apache Camel 2.7.2 released
The first came from Hadrian announcing the new release of Apache Camel, which is a poweful open source integration framework based on the well known “Enterprise Integration Patterns”’s book written by Gregor Hohpe and Bobby Woolf
.
This new version of the project (2.7.2) is primary focused on minor fixes and it’s a patch release that you can read them all here. I’ll provide you a minor list:
:
- Better usability of the OSGi environments
- Minor fixes for the camel-web console
- Minor fix for camel-ehcache related to replication across nodes
Download from here and try it.
Apache Whirr 0.5.0-incubating released
The second message is from Tom White, the author of a”Hadoop: The Defitive Guide” 2nd Edition’s book and one of the members of the Hadoop Project PMC; describing the fifth incubating release of this useful project, which is a set of tools for running cloud services such Apache Hadoop, HBase, ZooKeeper and Cassandra.
You can download it from here and you can view the full change log here.
Apache Cassandra 0.8 released
The last new today but very important too, at least for me, is the new release of Apache Cassandra, a distributed storage system for managing very large amounts of structured data spread out across many commodity servers, while providing highly available service with no single point of failure
.
The message from Eric Evans is very clear: I am very pleased to announce the official release of Cassandra 0.8.0. If you haven’t been paying attention to this release, this is your last chance, because by this time tomorrow all your friends are going to be raving, and you don’t want to look silly. So why am I resorting to hyperbole? Well, for one because this is the release that debuts the Cassandra Query Language (CQL). In one fell swoop Cassandra has become more than NoSQL, it’s MoSQL. Cassandra also has distributed counters now. With counters, you can count stuff, and counting stuff rocks. A kickass use-case for Cassandra is spanning data-centers for fault-tolerance and locality, but doing so has always meant sending data in the clear, or tunneling over a VPN. New for 0.8.0, encryption of intranode traffic. If you’re not motivated to go upgrade your clusters right now, you’re either not easily impressed, or you’re very lazy. If it’s the latter, would it help knowing that rolling upgrades between releases is now supported? Yeah. You can upgrade your 0.7 cluster to 0.8 without shutting it down. You see what I mean? Then go read the release notes[1] to learn about the full range of awesomeness, then grab a copy[2] and become a (fashionably )early adopter. Drivers for CQL are available in Python[3], Java[3], and Node.js[4]. As usual, a Debian package is available from the project’s APT repository[5]. Enjoy!
