Subject [jira] [Created] (ARROW-3410) [C++] Streaming CSV reader interface for memory-constrainted environments

-----------------------------------

             Summary: [C++] Streaming CSV reader interface for memory-constrainted environments
                 Key: ARROW-3410
                 URL: https://issues.apache.org/jira/browse/ARROW-3410
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
             Fix For: 0.12.0


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
