Class TopologyAwareSyncConsistentHashFactory

  • All Implemented Interfaces:
    ConsistentHashFactory<DefaultConsistentHash>

    public class TopologyAwareSyncConsistentHashFactory
    extends SyncConsistentHashFactory
    A ConsistentHashFactory implementation that guarantees caches with the same members have the same consistent hash and also tries to distribute segments based on the topology information in TransportConfiguration.

    It has a drawback compared to DefaultConsistentHashFactory: it can potentially move a lot more segments during a rebalance than strictly necessary.

    It is not recommended using the TopologyAwareSyncConsistentHashFactory with a very small number of segments. The distribution of segments to owners gets better with a higher number of segments, and is especially bad when numSegments &lt; numNodes
