Hector - a Java Cassandra client
I've written a java library for cassandra I've been using internally, would love to get your feedback and hope you find it useful. Blog post: http://prettyprint.me/2010/02/23/hector-a-java-cassandra-client/ Source: http://github.com/rantav/hector High level features: o A high-level object oriented interface to cassandra. In short: just some nicities around thrift. o Failover support. If a client is connected to one host in the ring and this host goes down, the client will automatically and transparently search for other available hosts to perform the operation before giving up. You may choose to FAIL_FAST (no retry, just fail if there are errors, nothing smart), ON_FAIL_TRY_ONE_NEXT_AVAILABLE (try one more host before giving up) or ON_FAIL_TRY_ALL_AVAILABLE (try all available hosts before giving up). o Connection pooling. Needless to say, it's a must. o JMX support. Hector exposes JMX for many runtime metrics, such as number of available connections, idle connections, error statistics etc. o Support for the Command design pattern to allow clients to concentrate on their business logic and let hector take care of the required plumbing.

Hi Ran, Is it support operation on super column ?

Re: Hector - a Java Cassandra client
it supports supercolumns, yes although I personally have only used regular columns so far (you can see the unit tests here http://github.com/rantav/hector/blob/master/src/test/java/me/prettyprint/cassandra/service/KeyspaceTest.java, search for super) On Tue, Feb 23, 2010 at 4:25 PM, Richard Grossman rich...@bee.tv wrote: Hi Ran, Is it support operation on super column ?
