Parth Chandra reopened DRILL-4313:
----------------------------------
Assignee: Parth Chandra
With Tableau, even with pooling enabled, this fix does not appear to improve
the distribution of the queries to different drillbits. The fix does improve
the distribution of queries in the test program, but not when used by Tableau.
The only solution might be for the client library to implement a pool of
connections and manage the distribution of queries under the covers.

>
> The current C++ client handles multiple parallel queries over the same
> connection, but that creates a bottleneck as the queries get sent to the same
> drillbit.
> The client can manage this more effectively by choosing from a configurable
> pool of connections and round robin queries to them.
