                <link>https://jira.mongodb.org/browse/DOCS-11167</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;In our documents about &lt;a href=&quot;https://docs.mongodb.com/manual/core/read-preference/#counter-indications&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ReadPreference&lt;/a&gt; said:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;For queries of sharded collections, for clusters with the balancer active, secondaries may return stale results with missing or duplicated data because of incomplete or terminated chunk migrations.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;Beginning in 3.6, this is still true by default. However, we now have readConcern=local/majority which makes secondaries &quot;chunk aware&quot;.&lt;/p&gt;</description>
