            <title>[SERVER-85871] Don&apos;t signal oplog waiters under ReplicationCoordinator mutex</title>
                <link>https://jira.mongodb.org/browse/SERVER-85871</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Something I noticed while analyzing work done under the ReplicationCoordinator mutex is that we signal all &lt;a href=&quot;https://github.com/mongodb/mongo/blob/90b40b58dc32403996649baf1f54a604d1e3b657/src/mongo/db/repl/replication_coordinator_external_state_impl.cpp#L1214&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;tailable oplog waiters&lt;/a&gt; while advancing the committed snapshot, which seems unnecessary and costly to do while holding the mutex. The CappedInsertNotifier already has its own &lt;a href=&quot;https://github.com/mongodb/mongo/blob/90b40b58dc32403996649baf1f54a604d1e3b657/src/mongo/db/storage/record_store.cpp#L149-L151&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mutex&lt;/a&gt;.&lt;/p&gt;</description>
