Work on IMPALA-11474 started by Noemi Pap-Takacs. ------------------------------------------------- > Codegen Tuple size in Sorter > ---------------------------- > > Key: IMPALA-11474 > URL: https://issues.apache.org/jira/browse/IMPALA-11474 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Reporter: Noemi Pap-Takacs > Assignee: Noemi Pap-Takacs > Priority: Minor > > The sorter works with fixed-length tuples. The number of bytes in a tuple is > known before execution, it is available in the query plan. However, currently > the tuple size is treated as a member variable of the TupleSorter. Using > Codegen to replace this member variable by a constant in sorter-ir.cc could > speed up the quicksort phase. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
