Change subject: IMPALA-3816 Codegen perf critical loops in Sorter ...................................................................... Patch Set 7: (8 comments) Thanks a lot Csaba and Daniel! On the comment "if 'CodegenFnPtr<Sorter::SortHelperFn> codegend_sort_helper_fn_' could be owned by Sorter::TupleSorter instead of SortPlanNode and PartialSortPlanNode. It seems that Sorter::TupleSorter is responsible for both codegening and calling it." There is a timing between the codegen and the use of the codegened method, where the former is done for the plan node in general throughout the code base, originated from FragmentInstanceState::Open() via InvokeCodegen(). http://gerrit.cloudera.org:8080/#/c/16621/7//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/16621/7//COMMIT_MSG@7 PS7, Line 7: IMPALA-3816 Codegen perf critical loops in Sorter > nit: missing : Done http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/partial-sort-node.h File be/src/exec/partial-sort-node.h: http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/partial-sort-node.h@45 PS7, Line 45: TupelSorter > Typo: TupleSorter.
