            <title>[SERVER-22564] ReplicaSetMonitor might not discover all hosts in a replica set for over 10 seconds</title>
                <link>https://jira.mongodb.org/browse/SERVER-22564</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When we create a ReplicaSetMonitor for a replica set for the first time we don&apos;t kick off a refresh of that replica set.  The ReplicaSetMonitorManager will eventually refresh it, but it only refreshes all sets once every 10 seconds.  This means there can be a period of 10 seconds or more (if it has to wait for other sets to be refreshed first) before all nodes of a replica set are discovered.  This can cause us to neglect certain secondaries for secondary reads, preventing us from evenly distributing the read load of secondary reads until after the full refresh takes place.&lt;/p&gt;</description>

The change affects the way ReplicaSetMonitor &quot;watcher&quot; thread runs, so it may need affect drivers.&lt;/p&gt;</comment>

                            <comment id="1244337" author="misha.tyulenev" created="Fri, 22 Apr 2016 20:01:59 +0000"  >&lt;p&gt;There are two delay issues here: &lt;br/&gt;
a)   &lt;a href=&quot;https://github.com/mongodb/mongo/blob/v3.2.3/src/mongo/client/replica_set_monitor.cpp#L130-L137&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/v3.2.3/src/mongo/client/replica_set_monitor.cpp#L130-L137&lt;/a&gt; which a temp patch until &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-7533&quot; title=&quot;Expose method to the mongo shell to get the status of a ReplSetMonitor instance&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-7533&quot;&gt;&lt;del&gt;SERVER-7533&lt;/del&gt;&lt;/a&gt; is fixed. It can be fixed  as this delay is not required anymore.&lt;br/&gt;
b)   The scan goes over all replica sets so that can take time until RS is refreshed. &lt;/p&gt;</comment>
