      Description

      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
