[GitHub] flink issue #2628: [FLINK-3722] [runtime] Don't / and % when sorting
Github user ggevay commented on the issue: https://github.com/apache/flink/pull/2628 > I transcribed Quicksort so as to remove considerations of Java performance and inlining. It was not clear to me that if we encapsulated the index, page number, and page offset into an object that Java would inline the various increment and decrement functions. Also, I don't think this looks too bad. I'm happy to reformat if that is preferred. OK, I would say that it is OK like this, but let's see what the others will say. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user greghogan commented on the issue: https://github.com/apache/flink/pull/2628 Thanks @ggevay for reviewing. I added a commit with additional comments. I transcribed `Quicksort` so as to remove considerations of Java performance and inlining. It was not clear to me that if we encapsulated the index, page number, and page offset into an object that Java would inline the various increment and decrement functions. Also, I don't think this looks too bad. I'm happy to reformat if that is preferred. I think this is the best time to investigate alternative methods. I'm not seeing how one would sort on top of `InMemorySorter` without deserializing records. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user StephanEwen commented on the issue: https://github.com/apache/flink/pull/2628 Thanks for these cool experiments. Looks like a nice improvement. I'll try to dig into your code in the next days... --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
