Astyanax is currently in use at Netflix. Issues generally are fixed as quickly as possbile and releases done frequently.

Some features provided by this client:

o high level, simple object oriented interface to cassandra
o failover behavior on the client side
o Connection pool abstraction. Implementation of a round robin connection pool.
o Monitoring abstraction to get event notification from the connection pool
o complete encapsulation of the underlying Thrift API and structs
o automatic retry of downed hosts
o automatic discovery of additional hosts in the cluster
o suspension of hosts for a short period of time after several timeouts
o annotations to simplify use of composite columns
