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

             Summary: would zookeeper transaction(multi) block the concurrent read?
                 Key: ZOOKEEPER-3049
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3049
             Project: ZooKeeper
          Issue Type: Wish
            Reporter: wayne


For instance, the original data for znode1 and znode2 are 2 and 4 respectively. I want to perform
increment operations over them. Finally, I would get (3, 5) for znode1 and znode2. In order
to keep atomicity, I used multi() api. Is there any possibility that any clients could read
(3, 4) concurrently? That is, the read happened after znode1++ and before znode2++?
