[I] Query execution path is accessing metadata in zookeeper through Quota Managers [pinot]

vrajat opened a new issue, #14852:
URL: https://github.com/apache/pinot/issues/14852

   Query execution code path should not access zookeeper as zookeeper locks & workload will affect its latency. TableCache and BrokerRoutingManagers use listeners to load a cache which is then used by the query.
   
   Similarly quota managers should also access quota metadata through a cache. I've attached a JFR and screenshots to show this issue.
