@sethah This is a nice optimization! Small suggestion -- For the shuffle
write performance improvement, would it be possible to test this on a larger
dataset to highlight the improvements and also to verify that other performance
characteristics did not change (eg the duration, which @MLnick mentioned went
up very slightly, although it seems due to a good reason, #rows was different)?
