            <title>[DOCS-11039] Docs for SERVER-31941: Disallow retryable writes in storage engines which do not support document-level locking</title>
                <link>https://jira.mongodb.org/browse/DOCS-11039</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h1&gt;&lt;a name=&quot;DocumentationRequestSummary%3A&quot;&gt;&lt;/a&gt;Documentation Request Summary: &lt;/h1&gt;

&lt;p&gt;No documentation summary in engineering ticket&lt;/p&gt;

&lt;h1&gt;&lt;a name=&quot;EngineeringTicketDescription%3A&quot;&gt;&lt;/a&gt;Engineering Ticket Description:&lt;/h1&gt;

&lt;p&gt;While retryable writes works in MMAPV1, due to the collection-level locking its performance is so bad that it cannot be used in practice. Because of this, we should disable retryable writes if &lt;tt&gt;StorageEngine::supportsDocLocking() == false&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;The effective behaviour should be that if the storage engine doesn&apos;t support document-level locking, any requests which include a txnNumber should fail with code &lt;tt&gt;UnsupportedOperation&lt;/tt&gt;.&lt;/p&gt;</description>
