             Summary: Notify listeners without holding the shared topology lock
                 Key: ISPN-9468
                 URL: https://issues.jboss.org/browse/ISPN-9468
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 9.4.0.CR1
            Reporter: Wolf-Dieter Fink


Post-write listeners are invoked from {{ClusteringDependentLogic.commitSingleEntry()}}, while holding the shared topology lock. We should be able to release the topology lock before invoking listeners, so that slow listeners (e.g. clustered/client listeners) don't delay the installation of a new topology.

Going further, we could try to use optimistic locking (e.g. with a {{StampedLock}}) instead of the {{ReentrantReadWriteLock}}, reverting the data container write if the topology changes and we are no longer an owner. This could help in scenarios where the data container update itself is slow, e.g. when using passivation with a JDBC/remote store.
