Class InvalidationInterceptor

java.lang.Object
  org.infinispan.commands.AbstractVisitor
      org.infinispan.interceptors.base.CommandInterceptor
          org.infinispan.interceptors.base.BaseRpcInterceptor
              org.infinispan.interceptors.InvalidationInterceptor

All Implemented Interfaces:

Visitor

public class InvalidationInterceptor
extends BaseRpcInterceptor

This interceptor acts as a replacement to the replication interceptor when the CacheImpl is configured with ClusteredSyncMode as INVALIDATE.

The idea is that rather than replicating changes to all caches in a cluster when write methods are called, simply broadcast an InvalidateCommand on the remote caches containing all keys modified. This allows the remote cache to look up the value in a shared cache loader which would have been updated with the changes.

Since:

4.0
