Class StateTransferInterceptor

java.lang.Object

org.infinispan.interceptors.BaseAsyncInterceptor

org.infinispan.interceptors.DDAsyncInterceptor

org.infinispan.interceptors.impl.BaseStateTransferInterceptor

org.infinispan.statetransfer.StateTransferInterceptor

All Implemented Interfaces:

org.infinispan.commands.Visitor, AsyncInterceptor

public class StateTransferInterceptor
extends org.infinispan.interceptors.impl.BaseStateTransferInterceptor

This interceptor has two tasks:

1. If the command's topology id is higher than the current topology id, wait for the node to receive transaction data for the new topology id.
2. If the topology id changed during a command's execution, retry the command, but only on the originator (which replicates it to the new owners).

If the cache is configured with asynchronous replication, owners cannot signal to the originator that they saw a new topology, so instead each owner forwards the command to all the other owners in the new topology.
