            <title>[SERVER-31263] distinct command should pass routingInfo to scatterGather()</title>
                <link>https://jira.mongodb.org/browse/SERVER-31263</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The distinct command &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.5.13/src/mongo/s/commands/commands_public.cpp#L1110-L1135&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;orders results according to the collection&apos;s default collation&lt;/a&gt; if the collection is sharded.&lt;/p&gt;

&lt;p&gt;It obtains the collection&apos;s default collation from the routingInfo. However, since scatterGather() internally gets its own copy of routingInfo, the routingInfo used in the command can be for a previous incarnation of the collection (and so have the wrong collection default collation).&lt;/p&gt;

&lt;p&gt;This ticket should make the versioned scatterGather() methods optionally take the routingInfo to use, for commands that need to use the routingInfo themselves for non-routing purposes.&lt;/p&gt;</description>
