&lt;p&gt;Shard by Combine a Natural and Synthetic Key&lt;br/&gt;
MongoDB supports compound shard keys that combine the best aspects of sharding by a evenly distributed key in the set and sharding by a random key. In these situations, the shard key would resemble &lt;/p&gt;
{ path: 1 , ssk: 1 }
&lt;p&gt; where, path is an often used &#8220;natural key, or value from your data and ssk is a hash of the _id field. &lt;/p&gt;

&lt;p&gt;how can we generate a ssk during insert ?&lt;/p&gt;</description>
