            <title>[SERVER-28113] which scene can lead to relocate the document phyisical order</title>
                <link>https://jira.mongodb.org/browse/SERVER-28113</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;we have a scene that we need traverse the whole collection ,and also record where we traverse to so that we can continue to do it if process failed,&lt;br/&gt;
I try update and delete some documents and db.collecton.find() return the same order but I can&apos;t find some issue to explain whether it is clustered index about wiredTiger. In MMAP I know it could change the location of data and find() return unordered.&lt;br/&gt;
So I want to confirm in wiredtiger  whether some operations can lead to db.collection.find() return unordered not include chunk moving in th shard or wiredtiger use clustered index ?&lt;/p&gt;</description>

&lt;p&gt;Thanks for your report.  If sort order is important for your application, I would recommend using an index rather than relying on the &lt;tt&gt;$natural&lt;/tt&gt; sort.&lt;/p&gt;

&lt;p&gt;Please note that SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the &lt;a href=&quot;http://groups.google.com/group/mongodb-user&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;mongodb-user group&lt;/a&gt; or &lt;a href=&quot;http://stackoverflow.com/questions/tagged/mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Stack Overflow with the &lt;tt&gt;mongodb&lt;/tt&gt; tag&lt;/a&gt;. A question like this involving more discussion would be best posted on the mongodb-users group.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;
Thomas&lt;/p&gt;</comment>
