            <title>[SERVER-15354] Implementing cluster index for RocksDB</title>
                <link>https://jira.mongodb.org/browse/SERVER-15354</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;In most cases, querys are focused on the same shardkey, so implementing a cluster index on shardkey will be very friendly for query.&lt;/p&gt;

&lt;p&gt;RocksDB can sort data by the key, so there can be a way to do this.&lt;/p&gt;

&lt;p&gt;Thanks&lt;/p&gt;</description>

I wasn&apos;t entirely sure whether this was referring to a clustered index or not. I guess this is a pretty decent sized feature, but it would be very cool to have.&lt;/p&gt;</comment>
                            <comment id="824461" author="dan@10gen.com" created="Sun, 8 Feb 2015 21:59:52 +0000"  >&lt;p&gt;This ticket refers to creating a clustered index, that is, storing the data in index-sorted order.  See: &lt;a href=&quot;http://en.wikipedia.org/wiki/Database_index#Clustered&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://en.wikipedia.org/wiki/Database_index#Clustered&lt;/a&gt;.  The advantage of having a clustered index on shard key is that logical &quot;chunks&quot; of data which are migrated from shard to shard are also physically stored contiguously on disk.&lt;/p&gt;</comment>

I just got a huge speedup for RocksDB by fixing &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-15793&quot; class=&quot;external-link&quot; rel=&quot;nofollow&quot;&gt;https://jira.mongodb.org/browse/SERVER-15793&lt;/a&gt; on my machine. What do you mean by a &quot;cluster index on shardkey&quot;?&lt;/p&gt;</comment>
