| <p>Moves data from MySql to Hive. The operator runs your query against |
| MySQL, stores the file locally before loading it into a Hive table. |
| If the <code class="docutils literal notranslate"><span class="pre">create</span></code> or <code class="docutils literal notranslate"><span class="pre">recreate</span></code> arguments are set to <code class="docutils literal notranslate"><span class="pre">True</span></code>, |
| a <code class="docutils literal notranslate"><span class="pre">CREATE</span> <span class="pre">TABLE</span></code> and <code class="docutils literal notranslate"><span class="pre">DROP</span> <span class="pre">TABLE</span></code> statements are generated. |
| Hive data types are inferred from the cursor’s metadata. Note that the |
| table generated in Hive uses <code class="docutils literal notranslate"><span class="pre">STORED</span> <span class="pre">AS</span> <span class="pre">textfile</span></code> |
| which isn’t the most efficient serialization format. If a |
| large amount of data is loaded and/or if the table gets |
| queried considerably, you may want to use this operator only to |
| stage the data into a temporary table before loading it into its |
| final destination using a <code class="docutils literal notranslate"><span class="pre">HiveOperator</span></code>.</p> |
