Subject Re: [DISCUSS] FLIP-18: Code Generation for improving sorting performance
Date Tue, 04 Apr 2017 00:46:39 GMT
Hi guys,

I have made an additional optimization[1] related to megamorphic call issue
that Greg mentioned earlier. The optimization[2] improves execution time
around ~13%, while the original code from FLINK-5734 is ~11%.

IMHO, the improvement from metamorphic call optimization is very small
compared to the code we have to introduce. So, I think we can just go with
the PR that we currently have. What do you think?
