Subject Re: Cassandra Clients for Java
Date Fri, 17 Jun 2011 22:36:56 GMT
My team prefers Pelops. https://github.com/s7/scale7-pelops

It's had failover since 0.7.
http://groups.google.com/group/scale7/browse_thread/thread/19d441b7cd000de0/624257fe4f94a037

With respect to avoiding writing marshaling code yourself, I agree with the
OP that that is rather lacking with these libraries themselves. DataNucleus
was recommended to me as a framework with the right abstractions to use
Cassandra as a JPA persistence provider, but I haven't had the time to
investigate.
