> I didn't expect this PR to have such a big performance improvement. Like #16443, I still don't understand why there is a performance improvement. I’m aware of two key differences: - Fewer redundant steps for `indices <--> batches` - Always keeping the right batch in cache (the original implementation performs a left-chunk × right-row iteration) However I was just hoping to cleanup the codebase a bit, I also didn’t expect it to be an easy 2X. -- This is an automated message from the Apache Git Service.
