> [Python][C++] Enable CSV reader to read from concatenated gzip stream
> ---------------------------------------------------------------------
>
> Key: ARROW-5974
> URL: https://issues.apache.org/jira/browse/ARROW-5974
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Affects Versions: 0.13.0, 0.14.0
> Reporter: Jordan Samuels
> Priority: Minor
>
> If two gzipped files are concatenated together, the result is a valid gzip
> file. However, it appears that pyarrow.csv.read_csv will only read the
> portion related to the first file.
> If the repro script
> [here|https://gist.github.com/jordansamuels/d69f1c22c58418f5dfa0785b9ecd211e]
> is run, the output is:
> {{$ python repro.py}}
> {{pyarrow.csv only reads one row:}}
> {{ x}}
> {{0 1}}
> {{pandas reads two rows:}}
> {{ x}}
> {{0 1}}
> {{1 2}}
> {{pyarrow version: 0.14.0}}
