> 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
> Priority: Major
>
> 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.
