            <title>[DOCS-10837] Docs for SERVER-31114: Perform targeted invalidation on direct writes to the `config.transactions` collection</title>
                <link>https://jira.mongodb.org/browse/DOCS-10837</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;Not sure if we document our internal collections, but this change treats the &lt;tt&gt;config.transactions&lt;/tt&gt; collection specially and only allows records with the following structure in it (all fields are mandatory):&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;_id (BSON) - BSON serialization of a logical session id&lt;/li&gt;
	&lt;li&gt;txnNum (int32) - The last transaction, which started on this session&lt;/li&gt;
	&lt;li&gt;lastWriteOpTimeTs (Timestamp) - The timestamp of the last oplog entry written for this session&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Deleting a document from this collection invalidates the session&apos;s transaction information, which means that all retryability information is lost for that session.&lt;/p&gt;

&lt;p&gt;Dropping this collection will break the retryable writes feature and must never be done by users. The collection will be automatically recreated on stepUp/stepDown.&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;As implemented, direct writes to the &lt;tt&gt;config.transactions&lt;/tt&gt; collection will invalidate the entire session transactions cache. This is not optimal, because session cleanup also performs direct writes to the sessions catalog and this can happen fairly frequently.&lt;/p&gt;

&lt;p&gt;Instead, when a document is available for the direct write, we should try to extract the session id from it and only invalidate that session.&lt;/p&gt;</description>
