             Summary: Pessimistic locking: transactions with more than one affected keys should replicate lock commands to all backups
                 Key: ISPN-5305
                 URL: https://issues.jboss.org/browse/ISPN-5305
             Project: Infinispan
          Issue Type: Bug
          Components: Core
            Reporter: Dan Berindei
            Assignee: Dan Berindei


Pessimistic locking includes an optimization to not replicate the lock command  to the backups if the transaction only affects a single key and the originator is the primary owner. However, the implementation is incorrect, and it checks each modification individually and it doesn't check if the transaction has more than one modification commands.

We should also make sure that when a second modification is added, we replicate the lock command for the first modification to its backup owners.
