Stress test for memory-based admission control

    XMLWordPrintableJSON

    Details

      Description

      We should extend the existing stress test to have a new mode designed to test memory-based admission control, where the stress test framework does not try to throttle memory consumption but instead relies on Impala doing so.

      The required changes would be:

      • A mode to disable throttling
      • Options for stricter pass conditions - queries should not fail with OOM even if the stress test tries to submit way too many queries.
      • However AC queue timeouts may be ok.
      • Investigation into the logic for choosing which query to run next and when - does that need to change?
