| <p>Arrow supports reading and writing columnar data from/to CSV files. |
| The features currently offered are the following:</p> |
| <ul class="simple"> |
| <li><p>multi-threaded or single-threaded reading</p></li> |
| <li><p>automatic decompression of input files (based on the filename extension, |
| such as <code class="docutils literal notranslate"><span class="pre">my_data.csv.gz</span></code>)</p></li> |
| <li><p>fetching column names from the first row in the CSV file</p></li> |
| <li><p>column-wise type inference and conversion to one of <code class="docutils literal notranslate"><span class="pre">null</span></code>, <code class="docutils literal notranslate"><span class="pre">int64</span></code>, |

| (disabled by default)</p></li> |
