            <title>[SERVER-9319] Allow to disable secondaries when they are behinded for a long time.</title>
                <link>https://jira.mongodb.org/browse/SERVER-9319</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I deployed a sharding cluster with 4 replica sets. Each rs contains a primary and a secondary and an arbiter. I insert data into primary and make queries on secondaries by using read preferrence &quot;SecondaryPreferred&quot;.&lt;br/&gt;
However, in some circumstance&#65292;my secondaries lag behind for a long time(eg. serveral hours) because of heavy load or hardware maintenance. In this circumstance, I actually don&apos;t want my app to read data from secondries becuse data in them are quite old. I prefer them to read from primary instead.&lt;/p&gt;

&lt;p&gt;So. Is it possible to add a config to specify a value, when the secondary find that it&apos;s&lt;br/&gt;
behind more than this time span,  it will turn to a &quot;CATCH UP&quot; status so that it&apos;s not a valid node temporary. And then &quot;SecondaryPreferred&quot; reads will be routed to primaries.&lt;/p&gt;</description>
