                <link>https://jira.mongodb.org/browse/SERVER-66899</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;The query SBE engine can access multiple collections at once via AutoGetCollection* helpers (so acquires multiple locks and accesses multiple Collection instances at once), but is currently limited to collections within the same database and only allowing a single collection to be sharded while the rest must be verified unsharded.&lt;/p&gt;</description>

                            <comment id="4665519" author="kaloian.manassiev" created="Fri, 8 Jul 2022 08:45:08 +0000"  >&lt;p&gt;The semantics of multiple database/collection versions is a way for a RouterRole to indicate to the ShardRole that it wants the relative placement of two database primaries/collection placement with respect to each other to be correct. The use-cases and the semantics of this are to be decided under WRITING-11362. For now, there are no use-cases for this.&lt;/p&gt;</comment>

Multiple database/collection versions is not what most people think it is.&lt;/p&gt;</comment>
