            <title>[DOCS-16264] [Server] Investigate changes in SERVER-78855: Use snapshot isolation for Queryable Encryption transactions</title>
                <link>https://jira.mongodb.org/browse/DOCS-16264</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;/div&gt;
&lt;p&gt;    Sharded transactions that use Query Encryption must set readConcern: snapshot. Other readConcern levels (local, majority) are disallowed. QE uses readConcern for internal transactions implicitly.&lt;/p&gt;

&lt;p&gt;Replica Set transactions have no limitations.&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    Use of distributed transactions involving multiple collections makes it more likely that users of QE will hit &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-77506&quot; title=&quot;Sharded multi-document transactions can mismatch data and ShardVersion&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-77506&quot;&gt;&lt;del&gt;SERVER-77506&lt;/del&gt;&lt;/a&gt;. Until it&apos;s resolved we should upgrade transactions used as part of QE to use snapshot read concern.&lt;/p&gt;
