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.
