[jira] [Created] (ARROW-504) [Python] Add adapter to write pandas.DataFrame in user-selected chunk size to streaming format

Wes McKinney created ARROW-504:
----------------------------------

             Summary: [Python] Add adapter to write pandas.DataFrame in user-selected chunk size to streaming format
                 Key: ARROW-504
                 URL: https://issues.apache.org/jira/browse/ARROW-504
             Project: Apache Arrow
          Issue Type: New Feature
            Reporter: Wes McKinney


While we can convert a {{pandas.DataFrame}} to a single (arbitrarily large) {{arrow::RecordBatch}}, it is not easy to create multiple small record batches -- we could do so in a streaming fashion and immediately write them into an {{arrow::io::OutputStream}}.
