Change subject: IMPALA-4252: Min-max runtime filters for Kudu ...................................................................... Patch Set 7: I know that He Lifu at NetEase also prototyped some support for pushing blooms down all the way into Kudu (not just the Impala scanner). On his TPCH benchmarks he got a ~50% speedup on Q17 and Q18, Q9, Q8, which I don't see in the results here. I wonder if this is due to a different partitioning scheme or whether the big gain actually comes from pushing all the way down into the Kudu scanner. Any idea, given the plans for those queries? -- 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 <[email protected]> Gerrit-Reviewer: Anonymous Coward #345 Gerrit-Reviewer: Lars Volker <[email protected]> Gerrit-Reviewer: Matthew Jacobs <[email protected]> Gerrit-Reviewer: Michael Ho <[email protected]> Gerrit-Reviewer: Mostafa Mokhtar <[email protected]> Gerrit-Reviewer: Thomas Tauber-Marshall <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Reviewer: Todd Lipcon <[email protected]> Gerrit-Comment-Date: Thu, 26 Oct 2017 20:35:31 +0000 Gerrit-HasComments: No
