Hello Thomas Tauber-Marshall, Mostafa Mokhtar, Alex Behm,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/8461
to look at the new patch set (#4).
Change subject: IMPALA-6151: add query-level fragment/backend counters
......................................................................
IMPALA-6151: add query-level fragment/backend counters
This adds NumBackends, NumFragments and NumFragmentInstances
counters to the query profile to make it easier to manually or
programmatically analyse the query.
Also add a num-queries-registered metric to track the number
of queries that have been executed but are not yet unregistered.
Testing:
Ran "select count(*) from alltypessmall" and checked profile:
Backend startup latencies: Count: 3, min / max: 1ms / 1ms, 25th %-ile: 1ms,
50th %-ile: 1ms, 75th %-ile: 1ms, 90th %-ile: 1ms, 95th %-ile: 1ms, 99.9th
%-ile: 1ms
Per Node Peak Memory Usage: tarmstrong-box:22000(1.10 MB)
tarmstrong-box:22001(1.02 MB) tarmstrong-box:22002(1.02 MB)
- FiltersReceived: 0 (0)
- FinalizationTimer: 0.000ns
- NumBackends: 3 (3)
- NumFragmentInstances: 4 (4)
- NumFragments: 2 (2)
Ran some queries and manually checked the num-queries-registered metric
on the /metrics page when the queries were running and after they
finished.
