I read some articles mentioning that Zookeeper watcher has latency issue.
Something like before the next watcher is placed and after the previous watcher
is triggered, it is possible that the client may not receive notification
within that period.

Then on the internet some people recommend using curator pathcache, which helps
watch child znodes being added, updated, etc. operations. So my question - is
it the right recipe to use if I want to avoid watcher latency problem?
Otherwise which recipe should I use instead or how to avoid such problem with
curator?
