            <title>[DRIVERS-1517] Investigate changes in PM-1769: Remove Code for enableMajorityReadConcern:false</title>
                <link>https://jira.mongodb.org/browse/DRIVERS-1517</link>
                <project id="10980" key="DRIVERS">Drivers</project>

    &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;Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;    Specific impacts will be documented as the project is implemented.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-color: #ccc;border-style: dashed;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;border-bottom-style: dashed;border-bottom-color: #ccc;background-color: #239eb0;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;Remove support for enableMajorityReadConcern:false since cache pressure concerns around majority commit point lag should be addressed with Durable History.&lt;/p&gt;

&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;

&lt;p&gt;The enableMajorityReadConcern:false is a mode of operation that does not allow distributed transactions, preventing Sharding from using distributed transactions internally. In addition, supporting this mode requires a large level of engineering effort. &lt;/p&gt;
