Package org.infinispan.interceptors.distribution

Class ScatteredDistributionInterceptor

  • All Implemented Interfaces:
    org.infinispan.commands.Visitor, AsyncInterceptor
    Direct Known Subclasses:
    BiasedScatteredDistributionInterceptor
    public class ScatteredDistributionInterceptor
extends org.infinispan.interceptors.impl.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.

        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.
