> Write query profile after sending final response to client to improve latency

> Key: DRILL-5123
> URL: https://issues.apache.org/jira/browse/DRILL-5123

> In testing a particular query, I used a test setup that does not write to the
> "persistent store", causing query profiles to not be saved. I then changed
> the config to save them (to local disk). This produced about a 200ms
> difference in query run time as perceived by the client.
> I then moved writing the query profile _after_ sending the client the final
> message. This resulted in an approximately 100ms savings, as perceived by the
> client, in query run time on short (~3 sec.) queries.
