            <title>[SERVER-74593] Unify RecordStore truncates</title>
                <link>https://jira.mongodb.org/browse/SERVER-74593</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;As part of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-74472&quot; title=&quot;Add support for truncating a given range in RecordStore&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-74472&quot;&gt;&lt;del&gt;SERVER-74472&lt;/del&gt;&lt;/a&gt; we had to add a new rangeTruncate method that is not tied to the same nuance as the normal truncate method.&lt;/p&gt;

&lt;p&gt;In particular, the two differ in the sense that:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;truncate clears out the oplog truncate markers, and clears the sizeStorer info&lt;/li&gt;
	&lt;li&gt;rangeTruncate expects the user to provide a hint for how much data it will remove and updates the sizeStorer information only&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The difference is subtle, but impedes fully merging the two methods without rewriting the current callers of truncate. Additionally, the Oplog truncate markers would have to be separated from living inside WiredTigerRecordStore in order to align the two methods&apos; behaviour.&lt;/p&gt;</description>

                            <comment id="5427481" author="JIRAUSER1264163" created="Tue, 16 May 2023 09:35:49 +0000"  >&lt;p&gt;With the introducion of the boundary &lt;a href=&quot;https://github.com/mongodb/mongo/blame/e9aea79d1d71e55fc40b43ba7d5894df8ab971c5/src/mongo/db/storage/record_store.cpp#L91&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;invariant&lt;/a&gt; we now force the ranged truncates to specify at least one boundary. This makes them impossible to behave as a full truncate so no unification is possible.&lt;/p&gt;

&lt;p&gt;As a result, we cannot unify the two methods, closing the ticket as Won&apos;t Fix.&lt;/p&gt;</comment>
