Andrew Wong created IMPALA-6821: ----------------------------------- Summary: Push down limits into Kudu Key: IMPALA-6821 URL: https://issues.apache.org/jira/browse/IMPALA-6821 Project: IMPALA Issue Type: Improvement Components: Clients Reporter: Andrew Wong
The progress made in KUDU-16 introduced a way to impose limits on Kudu scanners, potentially reducing the number of RPCs sent per scan, CPU used for scanner evaluation on the tablet server, etc. It would be nice if Impala could make use of this new behavior. I put up an admittedly clunky [patch|https://gerrit.cloudera.org/c/9923/] that implements limits on a per-token basis. I'm no Impala expert, so there may be an API missing in Kudu that would make Impala's life easier in implementing this. Maybe it's as easy as adjusting the limit after re-hydrating the token into a scanner. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
