Method Detail

consistentHash

public ConsistentHash consistentHash()

The consistent hash in use.

hash

public Hash hash()

The hash function in use. Used as a bit spreader and a general hash code generator. Typically one of the the many default ConsistentHash implementations shipped.

numOwners

public int numOwners()

Number of cluster-wide replicas for each cache entry.

numVirtualNodes

public int numVirtualNodes()

Controls the number of virtual nodes per "real" node. You can read more about virtual nodes in Infinispan's online user guide.

If numVirtualNodes is 1, then virtual nodes are disabled. The topology aware consistent hash must be used if you wish to take advnatage of virtual nodes.

A default of 1 is used.

rehashEnabled

@Deprecated
public boolean rehashEnabled()

Deprecated. Use StateTransferConfiguration.fetchInMemoryState() instead.

If false, no rebalancing or rehashing will take place when a new node joins the cluster or a node leaves

rehashRpcTimeout

@Deprecated
public long rehashRpcTimeout()

Deprecated. Use StateTransferConfiguration.timeout() instead.

Rehashing timeout

rehashWait

@Deprecated
public long rehashWait()

Deprecated. Use StateTransferConfiguration.timeout() instead.

groups

public GroupsConfiguration groups()

Configuration for various grouper definitions. See the user guide for more information.
