Gleb Kanterov commented on BEAM-8504:
-------------------------------------
[~aryann] yes, it looks like a backend or floating-point precision issue, it's
hard to tell for me because I didn't read proto or familiar with backend code.
The table is over 1B rows, and I can consistently reproduce it. I can do a PR
with revert, but I don't feel confident changing precondition without
understanding the codebase. It would be great if you can do that because I
think you know better.
