            <title>[DOCS-16283] [SERVER] Improve note about multi-doc transactions and WiredTiger cache pressure </title>
                <link>https://jira.mongodb.org/browse/DOCS-16283</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://www.mongodb.com/docs/v7.0/core/transactions-production-consideration/#wiredtiger-cache&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;This section&lt;/a&gt; states: &quot;If you have an uncommitted transaction that exceeds 5% of the WiredTiger cache size, the transaction will abort and return a write conflict error&quot;.&lt;/p&gt;

&lt;p&gt;As part of an unrelated investigation (&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64982&quot; title=&quot;Extended lack of availability caused by transactions&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64982&quot;&gt;SERVER-64982&lt;/a&gt;), we&apos;ve discovered that the statement is not accurate, and the by-design behaviour is more generic: an uncommitted transaction can abort and return a write conflict error if WiredTiger is under unsustainable cache pressure.&lt;/p&gt;

&lt;p&gt;(There&apos;s probably a more rigorous definition of &quot;unsustainable cache pressure&quot;. It&apos;s likely 20% or more of the cache content marked as dirty. However, this level of detail may be beyond what&apos;s expected in the manual, and we&apos;d need input from the WT team if we decided to include more colour around it.)&lt;/p&gt;</description>
