            <title>[SERVER-44390] Investigate whether we can run one DDL command per &apos;applyOps&apos;</title>
                <link>https://jira.mongodb.org/browse/SERVER-44390</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Today, multiple DDL commands can be specified in a single &apos;applyOps&apos; command. We should investigate if there are any use cases to having this and if we can only have one DDL command run per &apos;applyOps&apos;.&lt;/p&gt;

&lt;p&gt;There would be confusion on which lock mode to take for the database if we were to remove the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/be045feaf3ba4af8037c5baceda2b15cd2498a24/src/mongo/db/repl/apply_ops.cpp#L401&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;exclusive global lock here&lt;/a&gt; when there are multiple DDL commands to execute.&lt;/p&gt;

&lt;p&gt;If it&apos;s possible to run one DDL command per &apos;applyOps&apos; we can hold the appropriate lock mode throughout the entire operation for the database without the concern of having to switch lock modes for subsequent commands.&lt;/p&gt;</description>
