> By joining only one left row with the right batch at a time? However when `right_side_ordered == True` we need maintains right_side order. https://github.com/apache/datafusion/blob/69dfe6c499d39563f4e6d9835fcdf3793f7d98c8/datafusion/physical-plan/src/joins/nested_loop_join.rs#L727-L728 Perhaps we can "Process the Cartesian Product Incrementally" by generating Cartesian Product of `(left_batch, right_batch[i, i+N])` at a time I plan to implement "Limit intermediate_batch Size During Filtering" and "Yield Partial Batches on Demand" first, and then I will work on "Process the Cartesian Product Incrementally". cc @2010YOUY01 @xudong963 -- This is an automated message from the Apache Git Service.
