Wes McKinney updated ARROW-3410:
--------------------------------
Fix Version/s: (was: 0.14.0)
> [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
> Priority: Major
>
> 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
