I think @dstandish has a point here. In the beginning we planned to make four flat windows, but it was decided to nest them, and now I think for no reason at all. As the window values (row_numbers, sums) are assigned after partitioning is done, consistency and scheduling guarantees should be achieved. I will fix it ASAP to measure performance again, since now it's pretty slow, and the plan looks intimidating. Regarding the two windows that look similar - I doubt they can be replaced by one window due to different _partition by_ columns. Thanks for looking at the join conditions. I'll try to fix them too. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
