----------------------------------

             Summary: Provide option to save query profiles sync, async or not at all
                 Key: DRILL-5257
                 URL: https://issues.apache.org/jira/browse/DRILL-5257
             Project: Apache Drill
          Issue Type: Improvement
    Affects Versions: 1.10
            Reporter: Paul Rogers
            Assignee: Paul Rogers
            Priority: Minor
             Fix For: 1.10


DRILL-5123 improved perceived query performance by writing the query profile after sending
a final response to the client. This is the desired behaviors in most situations. However,
some tests want to verify certain results by reading the query profile from disk. Doing so
works best when the query profile is written before returning the final query results.

This ticket requests that the timing if the query profile writing be configurable.

* Sync: write profile before final client response.
* Async: write profile after final client response. (Default)
* None: don't write query profile at all

A config option (boot time? run time?) should control the option. A boot-time option is fine
for testing.
