             Summary: 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


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.
 * Show client RPC read/write/count stats in the query profile
