Tim Armstrong created IMPALA-8221:
-------------------------------------
Summary: 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
Assignee: Tim Armstrong
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.
