Class StateTransferLockInterceptor

java.lang.Object

org.infinispan.commands.AbstractVisitor

org.infinispan.interceptors.base.CommandInterceptor

org.infinispan.interceptors.StateTransferLockInterceptor

All Implemented Interfaces:

Visitor

public class StateTransferLockInterceptor
extends CommandInterceptor

An interceptor that blocks any commands when the StateTransferLock is locked.
To make the state transfer as short as possible, synchronous remote commands don't wait at all for the state transfer lock. So it's the originator's job to retry the command after the state transfer has ended. This interceptor handles the retries in handleWithRetries.

5.1
