Change subject: IMPALA-3816 Codegen perf critical loops in Sorter ...................................................................... IMPALA-3816 Codegen perf critical loops in Sorter This fix added the functionality to codegen method Sorter::TupleSorter::SortHelper() in sorter, which improves the performance for both the sort and the partial sort operators. In one unit testing to order 7300 rows from functional.alltypes, the speedup of the code-gen version of sort node is 29%. Testing: 1. Unit testing; 2. Ran Core tests successfully.
