Grant Henke commented on KUDU-646: ---------------------------------- [~adar] is this still relevant after all your changes and optimizations? > Check the scan type before applying the selection vector > -------------------------------------------------------- > > Key: KUDU-646 > URL: https://issues.apache.org/jira/browse/KUDU-646 > Project: Kudu > Issue Type: Improvement > Components: perf, tablet > Affects Versions: M5 > Reporter: Andrew Wang > Priority: Trivial > > As pointed out during code review of the MergeIterator, after merging the > selection vector is all true (all rows selected). > This means during a scan, if we are using the MergeIterator, we can skip > checking the resulting SelectionVector. This will save us some CPU. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
