> 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
