merlimat opened a new pull request #8348:
URL: https://github.com/apache/pulsar/pull/8348
### Motivation
Upgrade to latest stable ZK version 3.6.2. The new minor versions brings
several advantages:
* Performance improvements (eg: tuning group commit on txn log)
* Prometheus based metrics (so that we can get rid of AspectJ hacky way to
instrument ZK)
* New features like persistent recursive watches which would greatly
simplify the logic to handle metadata cache invalidations.
The possibility of rollback to previous version has also been validated.
