            <title>[SERVER-37847] Refactor cluster_aggregate to use one collation</title>
                <link>https://jira.mongodb.org/browse/SERVER-37847</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In a code review, Charlie pointed out that in &lt;tt&gt;dispatchShardPipeline()&lt;/tt&gt; we sometimes pass the collation &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c80ab84f6cc543071b045415a40b4b66795147c6/src/mongo/s/query/cluster_aggregate.cpp#L425-L432&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;from the request&lt;/a&gt; AggregationRequest when doing shard targeting, rather than passing &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c80ab84f6cc543071b045415a40b4b66795147c6/src/mongo/s/query/cluster_aggregate.cpp#L391&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;the collation&lt;/a&gt; which is the default for the collection (which is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c80ab84f6cc543071b045415a40b4b66795147c6/src/mongo/s/query/cluster_aggregate.cpp#L835-L896&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;computed here&lt;/a&gt;).&lt;/p&gt;

&lt;p&gt;We looked into it some more and could not find any incorrect behavior, but it might be worth doing a more thorough check, and refactor the code so that we only use one collation.&lt;/p&gt;</description>

Indeed it looks like this has been fixed. I think we can close this as &quot;Gone Away.&quot; IIRC Nick Zolnierz&#160;knows this code pretty well (and is the author of the relevant code in master), so I would just check with him before closing it.&lt;/p&gt;</comment>
