            <title>[SERVER-25015] Sharding balancer does not correctly obey tag ranges, which end in MaxKey</title>
                <link>https://jira.mongodb.org/browse/SERVER-25015</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;If a tag includes MaxKey as the max key, the logic in BalancerPolicy::getTagForChunk will misidentify the tag in which a chunk should go in certain cases. We should fix this and tighten the unit-tests around it.&lt;/p&gt;</description>
