Kurt Deschler resolved IMPALA-12176. ------------------------------------ Resolution: Fixed > Improve client fetch metrics > ---------------------------- > > Key: IMPALA-12176 > URL: https://issues.apache.org/jira/browse/IMPALA-12176 > Project: IMPALA > Issue Type: Improvement > Reporter: Kurt Deschler > Assignee: Kurt Deschler > Priority: Major > > These changes address limitations with the current metrics: > * ClientFetchWaitTimer includes both Thrift serialization/write and client > time. > * RowMaterializationTimer includes both coordinator fetch time and time to > convert rows to the client protocol. > Proposed changes: > * Add CreateResultSetTime metric to PLAN_ROOT_SINK node in the query > profile. This will isolate the cost to convert fetched rows to the client > protocol. > * Add read/write times for RPCs in /rpcz webui. These will be hidden by > default with a checkbox to enable display. > * Add sum to RPC histogram metrics > * Show client RPC read/write/count stats in the query profile -- This message was sent by Atlassian Jira (v8.20.10#820010)
