> CSV reads are currently all-or-nothing. If the results of parsing a CSV file
> do not fit into memory, this can be a problem. I propose to define a
> streaming {{RecordBatchReader}} interface so that the record batches produced
> by reading can be written out immediately to a stream on disk, to be memory
> mapped later
