> Well the hacky solution is just `EmitTo::First(batch_size)` until done 😄 I guess the concern is that it's not efficient because it's using `Vec::split_off` under the hood in most cases? Although that's not mandated by the API. But currently some plans simply don't work because of the memory overcounting. I think that will effectively copy all the values potentially total_size/batch_size times. But it will result in smaller allocations of record batches for sure -- This is an automated message from the Apache Git Service.
