Class LockingInterceptor

java.lang.Object
org.infinispan.interceptors.BaseAsyncInterceptor
org.infinispan.interceptors.DDAsyncInterceptor
org.infinispan.interceptors.locking.AbstractLockingInterceptor
org.infinispan.interceptors.locking.NonTransactionalLockingInterceptor
org.infinispan.hibernate.cache.commons.access.LockingInterceptor
All Implemented Interfaces:
org.infinispan.commands.Visitor, org.infinispan.interceptors.AsyncInterceptor
public class LockingInterceptor extends org.infinispan.interceptors.locking.NonTransactionalLockingInterceptor
With regular NonTransactionalLockingInterceptor, async replication does not work in combination with synchronous replication: sync replication relies on locking to order writes on backup while async replication relies on FIFO-ordering from primary to backup. If these two combine, there's a possibility that on backup two modifications modifications will proceed concurrently. Similar issue threatens consistency when the command has Flag.CACHE_MODE_LOCAL - these commands don't acquire locks either. Therefore, this interceptor locks the entry all the time. UnorderedDistributionInterceptor does not forward the message from non-origin to any other node, and the distribution interceptor won't block on RPC but will return CompletableFuture and we'll wait for it here.
