    Locking management in a multi-owner case

    Alain Brunet Newbie

      Gentlemen,

       

      I am trying to find out how Infinispan is managing locking in a multi-owner scenario. We are getting loads of deadlock since we do a lot of writes per seconds to a given cache element. We can manage them with the deadlock detection but it does impact seriously the throughput even with low lock acquisition timeout values.

       

      I was expecting a locking scheme were a single lock per element, no matter how much copies exists on the cluster, would be aquired leaving room for locking all other copies on the cluster without risking a deadlock. However what I observed is each node locking a copy and deadlocking when locking the other copies on the cluster.

       

      Any explanation is welcome.

      Thanks.

       

      Alain
