            <title>[SERVER-36279] Change the explain format for sharded aggregations to accomodate $exchange</title>
                <link>https://jira.mongodb.org/browse/SERVER-36279</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In a world where $exchange could be inserted theoretically anywhere in a sharded aggregation, it won&apos;t make sense to always present the &quot;splitPipeline&quot; in aggregation explain as a &quot;shardsPart&quot; and &quot;mergerPart&quot;.&lt;/p&gt;

&lt;p&gt;One potential format is to break up the pipeline into &quot;bubbles&quot;, where each one is separated by $exchange. At the exchange points, we could expose detail on which producers are feeding each consumer, to give a sense of how the routing is occurring.&lt;/p&gt;</description>
