Type Parameters:

CL -

All Implemented Interfaces:

ConnectionPool<CL>, SimpleHostConnectionPool.Listener<CL>

public class TokenAwareConnectionPoolImpl<CL>
extends AbstractHostPartitionConnectionPool<CL>

Connection pool that partitions connections by the hosts which own the token being operated on. When a token is not available or an operation is known to span multiple tokens (such as a batch mutate or an index query) host pools are picked using round robin. This implementation takes an optimistic approach which is optimized for a well functioning ring with all nodes up and keeps downed hosts in the internal data structures.
