Change subject: IMPALA-4252: Min-max runtime filters for Kudu ...................................................................... Patch Set 7: TPCDS is a better workload for min/max filtering than TPCH, because TPCDS relies on dynamic partition pruning to reduce scan size from the probe side of the joins. On the other hand min/max filtering won't help TPCH much because each partition from l_shipdate and o_orderdate will have the min and max values for l_orderkey and o_orderkey. -- To view, visit http://gerrit.cloudera.org:8080/7793 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I02bad890f5b5f78388a3041bf38f89369b5e2f1c Gerrit-Change-Number: 7793 Gerrit-PatchSet: 7 Gerrit-Owner: Thomas Tauber-Marshall <tmarsh...@cloudera.com> Gerrit-Reviewer: Anonymous Coward #345 Gerrit-Reviewer: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Matthew Jacobs <mjac...@apache.org> Gerrit-Reviewer: Michael Ho <k...@cloudera.com> Gerrit-Reviewer: Mostafa Mokhtar <mmokh...@cloudera.com> Gerrit-Reviewer: Thomas Tauber-Marshall <tmarsh...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Reviewer: Todd Lipcon <t...@apache.org> Gerrit-Comment-Date: Wed, 25 Oct 2017 02:50:26 +0000 Gerrit-HasComments: No
