            <title>[SERVER-57587] Avoid scheduling more range deletion tasks for same range during rename</title>
                <link>https://jira.mongodb.org/browse/SERVER-57587</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Currently, the &quot;idempotency&quot; of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/5a1ea618307b6f362202e283c3e180d8a71df3d5/src/mongo/db/s/range_deletion_util.cpp#L448-L465&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;restoreRangeDeletionTasksForRename&lt;/a&gt; is achieved by &lt;a href=&quot;https://github.com/mongodb/mongo/blob/5a1ea618307b6f362202e283c3e180d8a71df3d5/src/mongo/db/s/range_deletion_util.cpp#L457-L462&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;deleting previously &quot;renamed&quot; range deletion tasks and reschedule them with new migration ids&lt;/a&gt;. By doing so, the persistent state is clean but duplicate tasks are not unscheduled from the migration util executor.&lt;/p&gt;

&lt;p&gt;A better strategy would be to assign migrations id to snapshotted range deletions at an &lt;a href=&quot;https://github.com/mongodb/mongo/blob/5a1ea618307b6f362202e283c3e180d8a71df3d5/src/mongo/db/s/range_deletion_util.cpp#L443&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;early stage&lt;/a&gt; and afterwards simply check if the task has been already scheduled for the target collection.&lt;/p&gt;</description>
