  • Connection pool abstraction. Implementation of a round robin connection pool.
  • Monitoring abstraction to get event notification from the connection pool.
  • Complete encapsulation of the underlying Thrift API and structs.
  • Automatic retry of downed hosts.
  • Automatic discovery of additional hosts in the cluster.
  • Suspension of hosts for a short period of time after several timeouts.
  • Annotations to simplify use of composite columns.
