Patch Set 2: > Have you been able to run any perf tests with this change? I did some preliminary tests on the tpch_300_parquet.lineitem (which is ~67GB): Without the patch the INSERT INTO [] SELECT FROM [] query runs in ~320 seconds. With the patch the time comes down to ~185-215 seconds for the same query (variation because of latency). -- To view, visit http://gerrit.cloudera.org:8080/2905 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Iff9620d41ba0d5fb1aa0c9f4abb48866fc2b0698 Gerrit-PatchSet: 2 Gerrit-Project: Impala Gerrit-Branch: cdh5-trunk Gerrit-Owner: Sailesh Mukil <[email protected]> Gerrit-Reviewer: Henry Robinson <[email protected]> Gerrit-Reviewer: Marcel Kornacker <[email protected]> Gerrit-Reviewer: Mostafa Mokhtar <[email protected]> Gerrit-Reviewer: Sailesh Mukil <[email protected]> Gerrit-HasComments: No
