            <title>[SERVER-75639] Remove dedicated executor for moveChunk/moveRange commands</title>
                <link>https://jira.mongodb.org/browse/SERVER-75639</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-45338&quot; title=&quot;Make moveChunk robust to maxTimeMS expiring&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-45338&quot;&gt;&lt;del&gt;SERVER-45338&lt;/del&gt;&lt;/a&gt; added a dedicated mono-threaded executor to be used for &lt;tt&gt;moveChunk&lt;/tt&gt; commands (then moved to manage &lt;tt&gt;moveRange&lt;/tt&gt; commands starting from v6.0) but there seems to be no reason to keep on using a separate executor rather than picking a thread from the fixed executor.&lt;/p&gt;

&lt;p&gt;The reason behind &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1092edf1cc78103bf9e90cbb2fec24d167dcbae1/src/mongo/db/s/move_chunk_command.cpp#L309-L310&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this comment&lt;/a&gt; seems to be that the idea was having a one-threaded executor to guarantee that only one migration at a time could run, however the same guarantee is already provided &lt;a href=&quot;https://github.com/mongodb/mongo/blob/1cace66e813b95207985fb612bfcbb99dd733878/src/mongo/db/s/shardsvr_move_range_command.cpp#L95-L96&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;by the ActiveMigrationsRegistry&lt;/a&gt;.&lt;/p&gt;</description>
