            <title>[SERVER-46372] Use unordered object comparison in aggregation for finding inconsistent sharded indexes</title>
                <link>https://jira.mongodb.org/browse/SERVER-46372</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The aggregation used to find sharded indexes that aren&apos;t on all shards with chunks (added by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-44916&quot; title=&quot;Test and document a pipeline to find inconsistent indexes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-44916&quot;&gt;&lt;del&gt;SERVER-44916&lt;/del&gt;&lt;/a&gt; and modified by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-46084&quot; title=&quot;Don&amp;#39;t use $setUnion in aggregation for finding inconsistent sharded indexes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-46084&quot;&gt;&lt;del&gt;SERVER-46084&lt;/del&gt;&lt;/a&gt;) only considers a subset of the possible properties in an index specification when comparing them to work around the inability to cleanly compare BSON objects ignoring field order in aggregation. After&#160;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-29425&quot; title=&quot;Add an expression to sort an array&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-29425&quot;&gt;&lt;del&gt;SERVER-29425&lt;/del&gt;&lt;/a&gt; adds official support for ordering an array, the pipeline should be updated to compare entire index specifications with unordered object comparisons using $objToArray, the new sort expression, and then $arrayToObj.&lt;/p&gt;</description>
