As the developer of hector I can only speak in favor of my child of love and I haven't tried pelops so take the following with a grain of salt... Hector sees wide adoption and has been coined the de-facto java client. It's been in use in production critical systems since version 0.5.0 by a few companies. The development team is responsive and accepts patches from the community and is busy with new features and improvements all the time. There's a bug tracking system and all bugs are fixed very fast. There are two active mailing lists one for the developers and one for the users http://wiki.github.com/rantav/hector/mailing-lists (85 members) The project is maintained on github (http://github.com/rantav/hector) and the process in all is very transparent and open to the community. Code is well tested with an embedded version of cassandra which I contributed back to the main cassandra repository, it runs a mvn and an ant build and all release versions are available at http://github.com/rantav/hector/downloads including source code. We love contributions and want to make it as easy as possible to contribute back. I myself have made a few contributions to cassandra core so I'm well familiar with its internals, which doesn't hurt when you write a client... ...and finally the features (just the high level): - connection pooling - datacenter friendly - high level API - all public cassandra versions in the last 6 months - failover - simple LB - extensive JMX - well documented, many examples, wiki, mailing list, team of developers and contributors.
... and of course there's also thrift if you're into hacking on it...
