            <title>[SERVER-11338] GridFS  hash base sharding support</title>
                <link>https://jira.mongodb.org/browse/SERVER-11338</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;GridFS should be able to shard &lt;b&gt;fs.chunks&lt;/b&gt; collection using hash base sharding over &lt;b&gt;file_id&lt;/b&gt; field.&lt;br/&gt;
This would make it much more efficient in terms of even distribution of data across nodes. &lt;br/&gt;
Keep the uniqueness of pair &lt;b&gt;file_id&lt;/b&gt; + &lt;b&gt;n&lt;/b&gt; but be able to shard based on the hash. &lt;/p&gt;</description>

I believe this is a better idea is to support hashing a compound shard key of: &lt;p/&gt;
