<div class="section" id="mrs_01_24813__section197091051103919"><h4 class="sectiontitle">Scenario</h4><p id="mrs_01_24813__p15511464405">Loader accumulates a large amount of historical data during service running. The historical data may affect job submission, running, and status query, and even cause page freezing and job running failures. Therefore, you need to properly configure the historical data pruge policy based on the Loader service data volume.</p>
