            <title>[SERVER-83841] Simplify the VectorClock implementations</title>
                <link>https://jira.mongodb.org/browse/SERVER-83841</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;With &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-64863&quot; title=&quot;Interoperability issues between the VectorClock and the CatalogCache on secondary nodes of the CSRS&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-64863&quot;&gt;SERVER-64863&lt;/a&gt;, the &lt;em&gt;configTime&lt;/em&gt; is also gossiped-in on &lt;em&gt;configServers&lt;/em&gt;. With that change in place, the &lt;em&gt;gossipIn&lt;/em&gt;&#160;and&#160;&lt;em&gt;gossipOut&lt;/em&gt; functions become symmetrical, which might yield an opportunity to simply the general VectorClock implementation:&#160;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;It might be possible to get rid of the separate &lt;em&gt;gossipIn&lt;/em&gt; / &lt;em&gt;gossipOut&lt;/em&gt; methods, checking at the place where they are called (the only thing left is the trivial vector clock which doesn&apos;t gossip in or out anything, so we can perhaps even just make its gossiping methods to be noop).&lt;/li&gt;
	&lt;li&gt;For the replica-set case, it should be investigated whether there is harm to also include the config/topology time in the returned set &lt;span class=&quot;error&quot;&gt;&amp;#91;given that it will never have value sent, so these values will stay at zero&amp;#93;&lt;/span&gt;.&lt;/li&gt;
	&lt;li&gt;Because &lt;em&gt;configTime&lt;/em&gt; and &lt;em&gt;topologyTime&lt;/em&gt; are now being gossiped, we might be able to move the &lt;a href=&quot;https://github.com/10gen/mongo/blob/master/src/mongo/db/s/config_server_op_observer.cpp#L223&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;ticking&lt;/a&gt; of those clocks to the &lt;ins&gt;primary only&lt;/ins&gt;. This would also improve performance, as currently redundant work is performed when a node has reached a commit-point, that has a lower configTime/topologyTime, than what it has already learned through gossiping.&lt;/li&gt;
&lt;/ol&gt;
