            <title>[SERVER-85735] Make ExternalDataSourceScopeGuard a unique_ptr rather than shared_ptr</title>
                <link>https://jira.mongodb.org/browse/SERVER-85735</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-85453&quot; title=&quot;ExternalDataSourceScopeGuard should not be compatible with multiple plan executors&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-85453&quot;&gt;&lt;del&gt;SERVER-85453&lt;/del&gt;&lt;/a&gt; modified the external data source system so that its decoration on the client cursor is effectively a unique_ptr. However, making it a unique_ptr in practice proved to unveil some scope complications that violated intentional lock/operation ordering in run_aggregate.&lt;/p&gt;

&lt;p&gt;We should try to work around that to make it a unique_ptr so we can be confident the scope guard&apos;s lifecycle is as expected. We should also consider making it a member field in the client cursor, rather than a decoration (which will require some SCons library refactoring to avoid a dependency).&lt;/p&gt;</description>
