Because of this I think it makes no sense to implement this, so I am going to close it as Won&apos;t Fix.&lt;/p&gt;</comment>
                            <comment id="1645406" author="dianna.hohensee" created="Thu, 10 Aug 2017 18:11:43 +0000"  >&lt;p&gt;I wonder if this would annoy customers that try to use read concern &apos;available&apos; against a secondary that just received data, but not yet the corresponding metadata. Then they wouldn&apos;t be able to read it. Though maybe &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-30226&quot; title=&quot;Force the recipient shard to refresh its metadata after migration commit&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-30226&quot;&gt;&lt;del&gt;SERVER-30226&lt;/del&gt;&lt;/a&gt; would &lt;em&gt;mostly&lt;/em&gt; resolve that: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-30226&quot; title=&quot;Force the recipient shard to refresh its metadata after migration commit&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-30226&quot;&gt;&lt;del&gt;SERVER-30226&lt;/del&gt;&lt;/a&gt; is a best effort concept as well, so we aren&apos;t guaranteeing that the recipient has the new metadata and the behavior still exists.&lt;/p&gt;</comment>
