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