IMPALA-12385: Enable Periodic metrics by default This patch enables periodic metrics in query profiles by default and changes the metric collectors to be more suitable for mixed workloads. -Change default of resource_trace_ratio to 1 -Use samplng counters which can automatically resize for long queries -Reduce metric interval to 50ms to support short-running queries -Fragment metrics use the same sample interval as periodic metrics Testing: Updated runtime-profile-test and test_observability.py for new defaults Manual inspection of query profile metrics for long-running queries Change-Id: Ic8e5cbfd4b324081158574ceb8f4b3a062a69fd1 --- M be/src/runtime/query-state.cc M be/src/util/periodic-counter-updater.cc M be/src/util/runtime-profile-counters.h M be/src/util/runtime-profile-test.cc M be/src/util/runtime-profile.cc M be/src/util/streaming-sampler.h M common/thrift/Query.thrift M tests/query_test/test_observability.py 8 files changed, 34 insertions(+), 31 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/77/20377/1 -- To view, visit http://gerrit.cloudera.org:8080/20377 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: Ic8e5cbfd4b324081158574ceb8f4b3a062a69fd1 Gerrit-Change-Number: 20377 Gerrit-PatchSet: 1 Gerrit-Owner: Kurt Deschler <kdesc...@cloudera.com>
