Tim Armstrong reassigned IMPALA-8221:
-------------------------------------
Assignee: (was: Tim Armstrong)
> Stress test starts up queries too slowly
> ----------------------------------------
>
> Key: IMPALA-8221
> URL: https://issues.apache.org/jira/browse/IMPALA-8221
> Project: IMPALA
> Issue Type: Improvement
> Components: Infrastructure
> Reporter: Tim Armstrong
> Priority: Major
>
> The stress test is limited to submitting queries at < 1 per second by default
> because of this logic in the query producer:
> {code}
> sleep(1.0 / self.startup_queries_per_sec)
> {code}
> It would be good to remove this and make query submission faster and more
> bursty, to exercise more interesting code paths. E.g. use an exponential
> distribution to determine the gaps in submission times and submit a variable
> number of queries in each burst.
