            <title>[SERVER-9345] Reload sharded (collection) metadata in groups</title>
                <link>https://jira.mongodb.org/browse/SERVER-9345</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When reloading metadata for a database, all collections or a subset, we could do so in groups and in parallel to reduce the total for the reload.&lt;/p&gt;

&lt;p&gt;If you have 10000+ sharded collections and need to reload all their metadata in the chunk manager then it can take a long time (esp. if the config server is not local and on a higher latency network).&lt;/p&gt;</description>

Think reducing the metadata load in general and ensuring non-initial loads are fast would solve most of these problems.&lt;/p&gt;</comment>
