Cassandra hackfest and OSCON report

The best part of OSCON for me wasn't actually part of OSCON. The guys at Twitter put together a Cassandra hackfest on Wednesday night, with much awesomeness resulting. Thanks to Evan for organizing! Stu Hood flew up from Rackspace's Virginia offices just for the night, which normally probably wouldn't have been worth it, but Cliff Moon , author of dynomite , showed up (thanks, Cliff!) and was able to give Stu a lot of pointers on implementing merkle trees . Cliff and I also had a good discussion with Jun Rao about hinted handoff--Cliff and Jun are not fans, and I tend to agree with them--and eventual consistency . I also met David Pollack and got to talk a little about persistence for Goat Rodeo , and talked to a ton of people from Twitter and Digg. I think those two, with Rackspace and IBM Research, constituted the companies with more than one engineer attending. The rest was "long tail." Back at OSCON, my Cassandra talk was standing room only.

Cassandra 0.3 update

Two months after the first release candidate , Cassandra 0.3 is still not out. But, we're close! We had two more bug-fix release candidates, and it's virtually certain that 0.3-final will be the same exact code as 0.3-rc3 . (If you're using rc1, you do want to upgrade; see CHANGES.txt .) But, we got stuck in the ASF bureaucracy and it's going to take at least one more round-trip before the crack Release Prevention Team grudgingly lets us call it official. In the meantime, work continues apace on trunk for 0.4.
