@alamb it's definitely a kind of range join. Having generalized optimizations for that would definitely be welcome, but I think in this case I can outperform any join. Each partition I need to join within (field A) is fewer than 1000 rows and so it's embarrassingly parallelizable and extremely low memory usage. I need to solve how to do other filtering/slicing/grouping/etc of the output, though, which is why I'd like to expose it as a table/view to datafusion. -- This is an automated message from the Apache Git Service.
