Cassandra DB clients

Have been playing around with Cassandra for sometime. Cassandra is a hybrid of Dynamo and BigTable. More details on my experiences in a later post. This is just a placeholder to keep track of the growing list of Cassandra clients. Please let me know if you need to add one. (View a list of popular articles on Cassandra).

BTW I have tried only the Java Thrift interface. Works, but very basic and has to improve a lot. Other high level APIs are all evolving. Will comment as I get chance to try more. Twitter's fauna/cassandra (rb) and Digg's lazyboy (py) seems very promising. Looks like Digg has gone to production recently on Cassandra. Nodeta's scalandra (scala) was extracted from Flowdock.

Lowlevel:

Thrift

(java, cpp, csharp, php, perl, rb)

Highlevel:

Java
Start writing :) Wait you should be using Scala (jdk7)?

  2. BTW - clojure-cassandra has now been renamed to closet. http://github.com/mattrepl/closet

    I forked clojure-cassandra a while ago, so you can still get the original from github.com/viksit/clojure-cassandra.
