Package com.palantir.atlasdb.keyvalue.cassandra

Class CassandraClientPoolImpl

java.lang.Object

com.palantir.atlasdb.keyvalue.cassandra.CassandraClientPoolImpl

All Implemented Interfaces:

CassandraClientPool

public class CassandraClientPoolImpl
extends Object
implements CassandraClientPool

Feature breakdown: - Pooling - Token Aware Mapping / Query Routing / Data partitioning - Retriable Queries - Pool member error tracking / blacklisting* - Pool refreshing - Pool node autodiscovery - Pool member health checking*

*entirely new features

By our old system, this would be a RefreshingRetriableTokenAwareHealthCheckingManyHostCassandraClientPoolingContainerManager; ... this is one of the reasons why there is a new system.
