            <title>[SERVER-54301] Add correctness tests of recovery using history store</title>
                <link>https://jira.mongodb.org/browse/SERVER-54301</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/WT-7117&quot; title=&quot;RTS to skip modifies that are more recent than on-disk base update while restoring an update&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-7117&quot;&gt;&lt;del&gt;WT-7117&lt;/del&gt;&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/browse/WT-7159&quot; title=&quot;Always write on-disk update as a full update to history store&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-7159&quot;&gt;&lt;del&gt;WT-7159&lt;/del&gt;&lt;/a&gt;, we&apos;ve identified a gap in our MongoDB test coverage. We should ensure that we have adequate test coverage of MongoDB crash recovery that requires the use of the history store to catch future bugs in this space.&lt;/p&gt;

&lt;p&gt;See the workload described in &lt;a href=&quot;https://jira.mongodb.org/browse/WT-7159&quot; title=&quot;Always write on-disk update as a full update to history store&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-7159&quot;&gt;&lt;del&gt;WT-7159&lt;/del&gt;&lt;/a&gt; as an example of a workload in MongoDB that utilizes the history store and tests recovery.&lt;/p&gt;</description>
