Class ScatteredDistributionInterceptor

java.lang.Object

org.infinispan.interceptors.BaseAsyncInterceptor

org.infinispan.interceptors.DDAsyncInterceptor

org.infinispan.interceptors.impl.BaseRpcInterceptor

org.infinispan.interceptors.impl.ClusteringInterceptor

org.infinispan.interceptors.distribution.ScatteredDistributionInterceptor

All Implemented Interfaces:

Visitor, AsyncInterceptor

Direct Known Subclasses:

BiasedScatteredDistributionInterceptor

public class ScatteredDistributionInterceptor
extends ClusteringInterceptor

This interceptor mixes several functions: A) replicates changes to other nodes B) commits the entry C) schedules invalidation On primary owner, the commit is executed before the change is replicated to other node. If the command reads previous value and the version of entry in DataContainer has changed during execution ConcurrentChangeException is thrown and the command has to be retried.

singleWriteOnRemotePrimary

This method is called by a non-owner sending write request to the primary owner

manyWriteOnRemotePrimary

protected CompletionStage<ValidResponse> manyWriteOnRemotePrimary(Address target,
                                                                  WriteCommand command,

This is a hook for bias-enabled mode where the primary performs additional RPCs but replication to another node. The returned CF will be complete when both the provided rpcFuture completes and all additional RPCs are complete, too. Failure in any of the RPCs will fail this future.
