href="https://dev.mysql.com/doc/refman/8.0/en/load-data.html" target="_blank" rel="noopener noreferrer">LOAD DATA</a> syntax to import local files. MySQL Load is a synchronous import method where the import result is returned upon completion. That means users can tell whether the import suceeds from the returned result. Generally, the MySQL Load method can be used to ingest files smaller than 10GB in size. For files larger than 10GB, it is recommended to split them into smaller ones. MySQL Load ensures the atomicity of a batch of import tasks, meaning that either all imports succeed or all imports fail.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="applicable-scenarios">Applicable scenarios<a href="#applicable-scenarios" class="hash-link" aria-label="Direct link to Applicable scenarios" title="Direct link to Applicable scenarios"></a></h2><p><strong>Supported format</strong></p><p>MySQL Load is primarily designed for importing CSV files from the client&#x27;s local machine or importing data from data streams through programs.</p><p><strong>Restrictions</strong></p><p>When importing CSV files, it is important to differentiate between null values and empty strings (&#x27;&#x27;):</p><ul><li>Null values are represented by the escape sequence \N.

They both involve importing local files into the Doris cluster. Therefore, the implementation of MySQL Load reuses the basic import capabilities of Stream Load.</p><p>The main processes of MySQL Load include:</p><ol><li>The user submits a LOAD DATA request to the frontend (FE), which performs the parsing and encapsulates the request into a Stream Load task.</li><li>The FE selects a backend (BE) node and sends the Stream Load request to it.</li><li>Meanwhile, the FE reads the local file data from the MySQL client in an asynchronous and streaming manner and sends it in real time to the HTTP request of the Stream Load.</li><li>Once the data transfer from the MySQL client is complete, the FE waits for the Stream Load to finish and displays the import result (success or failure) to the client.</li></ol><h2 class="anchor anchorWithStickyNavbar_LWe7" id="get-started">Get started<a href="#get-started" class="hash-link" aria-label="Direct link to Get started" title="Direct link to Get started"></a></h2><h3 class="anchor anchorWithStickyNavbar_LWe7" id="preparations">Preparations<a href="#preparations" class="hash-link" aria-label="Direct link to Preparations" title="Direct link to Preparations"></a></h3><p>MySQL Load requires INSERT permission on the target table.
