[jira] [Created] (CURATOR-477) Ability to turn off Zk Watches in Curator Framework

Rama Chavali created CURATOR-477:
------------------------------------

             Summary: Ability to turn off Zk Watches in Curator Framework
                 Key: CURATOR-477
                 URL: https://issues.apache.org/jira/browse/CURATOR-477
             Project: Apache Curator
          Issue Type: Improvement
          Components: Framework
    Affects Versions: 4.0.1
            Reporter: Rama Chavali


In our use case, we use *{{TreeCache}}* to get Zk Data periodically. We start *{{TreeCache}}* read data and close it. In this use case, The {{ZkWatchManager}} of {{ZooKeeper}} class keeps growing for every TreeCache operation because new {{TreeNode}} objects are created and added there leading to a memory leak. Also since we do not want the Watcher to periodically watch, this creates unnecessary background operations.

Can we introduce a builder flag in CuratorFramework's Builder some thing called "createZkWatches" that we can use to turn the watchers off? The default would be set to true to retain the current behaviour.
