------------------------------------------

             Summary: Batch Writer implementation doesn't need to synchronize on addMutation(String,
Iterator)
                 Key: ACCUMULO-760
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-760
             Project: Accumulo
          Issue Type: Improvement
          Components: client
            Reporter: Christopher Tubbs
            Assignee: Christopher Tubbs
             Fix For: 1.5.0


org.apache.accumulo.core.client.impl.TabletServerBatchWriter locks when a mutation is added.
It does not need to lock when iterating through an Iterator<Mutation> to add them one
at a time. This can have add significant performance issues to the other threads servicing
the batch writer's bins if the Iterator that is passed in is poorly performing.
