> We put transient profiles in zookeeper and update state as query progresses
> and changes states. It is observed that this adds latency of ~45msec for each
> update in the query execution path. This gets even worse when high number of
> concurrent queries are in progress. For concurrency=100, the average query
> response time even for short queries is 8 sec vs 0.2 sec with these updates
> disabled. For short lived queries in a high-throughput scenario, it is of no
> value to update state changes in zookeeper. We need an option to disable
> these updates for short running operational queries.
