            <title>[SERVER-53776]  Create feature flag to guard incomplete DDL operations</title>
                <link>https://jira.mongodb.org/browse/SERVER-53776</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Until &lt;a href=&quot;https://jira.mongodb.org/issues/?jql=labels+%3D+PM-1965-Milestone-1&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;PM-1965-Milestone-1&lt;/a&gt; will be completed, the new DDL operations implementations won&apos;t be resilient to shutdown/stepdown and concurrent workloads. So we need to introduced a new feature flag that will prevent the concurrency and step-down suites to run incompleted DDL operations.&lt;/p&gt;

&lt;p&gt;The idea is that we will have two feature flags:&lt;br/&gt;
&#160;- &lt;tt&gt;featureFlagShardingDDLSupport&lt;/tt&gt;&lt;font color=&quot;#1d1c1d&quot;&gt;&lt;/font&gt;&#160;- &lt;tt&gt;featureFlagDisableIncompleteShardingDDLSupport&lt;/tt&gt;&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;&lt;tt&gt;ShardingDDLSupport&lt;/tt&gt; flag will be enable for all the &quot;all feature flags&quot; variants, while the &lt;tt&gt;DisableIncompleteShardingDDLSupport&lt;/tt&gt; flag will be enable in all the shutdown/stepdown suites.&lt;/p&gt;



&lt;p&gt;The new DDL operation&apos;s paths will be executed in the code only if:&lt;br/&gt;
&lt;tt&gt;(featureFlagShardingDDLSupport &amp;amp;&amp;amp; !featureFlagDisableIncompleteShardingDDLSupport)&lt;/tt&gt;&lt;/p&gt;

&lt;p&gt;So probably we need also to introduce a wrapper to hide this complexity around the featureFlag/FCV check.&lt;/p&gt;</description>
