Qifan Chen resolved IMPALA-4065. -------------------------------- Fix Version/s: Impala 4.0 Resolution: Fixed > Inline comparator calls into TopN::InsertBatch() > ------------------------------------------------ > > Key: IMPALA-4065 > URL: https://issues.apache.org/jira/browse/IMPALA-4065 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Affects Versions: Impala 2.7.0 > Reporter: Tim Armstrong > Assignee: Qifan Chen > Priority: Minor > Labels: codegen, ramp-up > Fix For: Impala 4.0 > > Attachments: > 0001-WIP-IMPALA-3816-IMPALA-4065-full-TupleRowComparator-.patch > > > This is the more interesting follow-on from IMPALA-3815. We should inline the > Compare() calls in the codegen'd TopN code to avoid the indirect function > pointer call. > The tricky aspect is that the Compare() calls are called from > std::priority_queue, and we don't have a way to force-inline those functions > at the moment. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
