Change subject: IMPALA-3816 Codegen perf critical loops in Sorter ...................................................................... Patch Set 7: (5 comments) Great work! Aside from the nits, I wonder 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. 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. http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/partial-sort-node.cc File be/src/exec/partial-sort-node.cc: http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/partial-sort-node.cc@26 PS7, Line 26: #include "runtime/sorter-internal.h" Nit: This include should come before "util/runtime-profile-counters.h" because of the alphabetical order. http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/sort-node.cc File be/src/exec/sort-node.cc: http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/exec/sort-node.cc@27 PS7, Line 27: #include "codegen/llvm-codegen.h" : #include "runtime/sorter-internal.h" Should be sorted alphabetically. http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/runtime/sorter-internal.h File be/src/runtime/sorter-internal.h: http://gerrit.cloudera.org:8080/#/c/16621/7/be/src/runtime/sorter-internal.h@442 PS7, Line 442: GENERAL The implementation doesn't return Status("GENERAL") but Status("Sorter::TupleSorter::Codegen(): failed to finalize function").
