                <link>https://jira.mongodb.org/browse/CDRIVER-1872</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;Calling mongoc_cursor_set_hint (&lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-1188&quot; title=&quot;Implement mongoc_cursor_set_hint()&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-1188&quot;&gt;&lt;del&gt;CDRIVER-1188&lt;/del&gt;&lt;/a&gt;) automatically sets the SlaveOkay bit. Normally this is correct since we intend to directly query a server, but via mongos setting SlaveOkay is equivalent to read preference &quot;secondaryPreferred&quot;.&lt;/p&gt;</description>
