            <title>[SERVER-24223] Add hash to minvalid OpTime boundaries</title>
                <link>https://jira.mongodb.org/browse/SERVER-24223</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In the case there is a rollback after/during a failed apply batch it is possible to fetch new oplog entries with matching OpTimes but different hashes when recovering and applying the batch again &amp;#8211; although very unlikely...&lt;/p&gt;


&lt;p&gt;Oplog-as-a-buffer will address this since we will always have the oplog entries locally.&lt;/p&gt;</description>

                            <comment id="1365271" author="redbeard0531" created="Tue, 23 Aug 2016 17:44:39 +0000"  >&lt;p&gt;Linking to &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-25756&quot; title=&quot;Replication should ensure that minValid is hit exactly&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-25756&quot;&gt;&lt;del&gt;SERVER-25756&lt;/del&gt;&lt;/a&gt; as a separate ticket since the hash isn&apos;t actually needed in PV1. Note that oplog-as-buffer only addresses this at steady state, we&apos;d need other mechanisms to fix this for other setters of minValid such as initial sync and rollback.&lt;/p&gt;</comment>
