Is your feature request related to a problem or challenge?

I think batch coalescer won't make this faster as this is buffering everything in memory anyway.

The main idea would be to apply the filters iteratively to the incoming RecordBatch instead of the indices, so we have to change the API / implementation a bit more.

@Dandandan mentions in #16443 that we apply filters to the RecordBatch when processing incoming batches in nested loop join.
