Hi all, I have been using apache zookeeper. Now I'm willing to switch to CuratorFramework as it contains many useful recipes inbuilt.
PathChildrenCache[1] is the solution you have provided to watch on a given node without using native zookeeper watchers. As I went through the API [1] documentation, the following ambiguous sentence has caused me to think twice as I want consistency accuracy for my implementation (such as not missing CHILD_CREATED events). "it's not possible to stay transactionally in sync. Users of this class must be prepared for false-positives and false-negatives. Additionally, always use the version number when updating data to avoid overwriting another process' change." Can anyone please clarify how the above effect can affect the accuracy of events listened? And is there a way to w atch on a given node without using Zookeeper watchers and PathChildrenCache? (PathChildrenCache has the functionality I required. But the above description in the API docs matters me) Thanks in advance!
