Todd Lipcon commented on KUDU-1644: ----------------------------------- Worth noting there's also the case where the merging of the DRS bounds with the IN-list can fully eliminate the DRS (ie the predicate converts to 'None') in which case the rowset can be skipped. I don't know if we implement that optimization today but seems again like an easy win. > Simplify IN-list predicate values based on tablet partition key or rowset PK > bounds > ----------------------------------------------------------------------------------- > > Key: KUDU-1644 > URL: https://issues.apache.org/jira/browse/KUDU-1644 > Project: Kudu > Issue Type: Sub-task > Components: tablet > Reporter: Dan Burkert > Priority: Major > > When new scans are optimized by the tablet, the tablet's partition key bounds > aren't taken into account in order to remove predicates from the scan. One > of the most important such optimizations is that IN-list predicates could > remove values based on the tablet's constraints. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
