| <p>Options for converting CSV data.</p> |
| <dl class="field-list simple"> |
| <dt class="field-odd">Parameters</dt> |
| <dd class="field-odd"><ul class="simple"> |
| <li><p><strong>check_utf8</strong> (<em>bool</em><em>, </em><em>optional</em><em> (</em><em>default True</em><em>)</em>) – Whether to check UTF8 validity of string columns.</p></li> |
| <li><p><strong>column_types</strong> (<em>pa.Schema</em><em> or </em><em>dict</em><em>, </em><em>optional</em>) – Explicitly map column names to column types. Passing this argument |
| disables type inference on the defined columns.</p></li> |
| <li><p><strong>null_values</strong> (<em>list</em><em>, </em><em>optional</em>) – A sequence of strings that denote nulls in the data |
| (defaults are appropriate in most cases). Note that by default, |
| string columns are not checked for null values. To enable |
| null checking for those, specify <code class="docutils literal notranslate"><span class="pre">strings_can_be_null=True</span></code>.</p></li> |
| <li><p><strong>true_values</strong> (<em>list</em><em>, </em><em>optional</em>) – A sequence of strings that denote true booleans in the data |
| (defaults are appropriate in most cases).</p></li> |
| <li><p><strong>false_values</strong> (<em>list</em><em>, </em><em>optional</em>) – A sequence of strings that denote false booleans in the data |
| (defaults are appropriate in most cases).</p></li> |
| <li><p><strong>timestamp_parsers</strong> (<em>list</em><em>, </em><em>optional</em>) – A sequence of strptime()-compatible format strings, tried in order |
| when attempting to infer or convert timestamp values (the special |
| value ISO8601() can also be given). By default, a fast built-in |
| ISO-8601 parser is used.</p></li> |
| <li><p><strong>strings_can_be_null</strong> (<em>bool</em><em>, </em><em>optional</em><em> (</em><em>default False</em><em>)</em>) – Whether string / binary columns can have null values. |
| If true, then strings in null_values are considered null for |
| string columns. |
| If false, then all strings are valid string values.</p></li> |
| <li><p><strong>auto_dict_encode</strong> (<em>bool</em><em>, </em><em>optional</em><em> (</em><em>default False</em><em>)</em>) – Whether to try to automatically dict-encode string / binary data. |
| If true, then when type inference detects a string or binary column, |
| it it dict-encoded up to <cite>auto_dict_max_cardinality</cite> distinct values |
| (per chunk), after which it switches to regular encoding. |
| This setting is ignored for non-inferred columns (those in |
| <cite>column_types</cite>).</p></li> |
| <li><p><strong>auto_dict_max_cardinality</strong> (<em>int</em><em>, </em><em>optional</em>) – The maximum dictionary cardinality for <cite>auto_dict_encode</cite>. |
| This value is per chunk.</p></li> |
| <li><p><strong>include_columns</strong> (<em>list</em><em>, </em><em>optional</em>) – The names of columns to include in the Table. |
| If empty, the Table will include all columns from the CSV file. |
| If not empty, only these columns will be included, in this order.</p></li> |
| <li><p><strong>include_missing_columns</strong> (<em>bool</em><em>, </em><em>optional</em><em> (</em><em>default False</em><em>)</em>) – If false, columns in <cite>include_columns</cite> but not in the CSV file will |
| error out. |
| If true, columns in <cite>include_columns</cite> but not in the CSV file will |
| produce a column of nulls (whose type is selected using |
| <cite>column_types</cite>, or null by default). |
| This option is ignored if <cite>include_columns</cite> is empty.</p></li> |
