            <title>[DOCS-11864] Zone Sharding example is misleading regarding behavior on documents outside of all tag ranges</title>
                <link>https://jira.mongodb.org/browse/DOCS-11864</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;----------------------------&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;OriginalDescription&quot;&gt;&lt;/a&gt;Original Description&lt;/h2&gt;

&lt;p&gt;&lt;a href=&quot;https://docs.mongodb.com/manual/core/zone-sharding/#zones&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://docs.mongodb.com/manual/core/zone-sharding/#zones&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;In the example, document&lt;/p&gt;

{ x : 23 }

&lt;p&gt;ends up on shard &quot;Charlie&quot;. This is indeed&#160;&lt;em&gt;possible&lt;/em&gt;. But it is not the only possibility. My testing showed that in the case of documents not covered by any of the configured tag ranges, those documents will be balanced among&#160;&lt;em&gt;all shards&lt;/em&gt;&#160;&#8211; those with and without a tag. So the&lt;/p&gt;

{ x : 23 }

&lt;p&gt;could end up on shard &quot;Charlie&quot;. But it could end up on &quot;Alpha&quot; or &quot;Beta&quot;, too. Showing it on &quot;Charlie&quot; incorrectly implies that it could&#160;&lt;em&gt;only&lt;/em&gt;&#160;end up there, which is not correct.&lt;/p&gt;

&lt;p&gt;Documents (again, per my testing) not falling in any tag range end up on shards with and without tags, not only on shards without tag. The example should make that clear &#8211; i.e, by showing document&lt;/p&gt;

{ x :25 }

&lt;p&gt;on shard alpha, and explaining why that happens.&lt;br/&gt;
----------------------------&lt;/p&gt;
&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Scopeofchanges%28filesthatneedworkandhowmuch%29&quot;&gt;&lt;/a&gt;Scope of changes (files that need work and how much)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Impacttootherdocsoutsideofthisproduct&quot;&gt;&lt;/a&gt;Impact to other docs outside of this product&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%28workanddate%3F%29&quot;&gt;&lt;/a&gt;MVP (work and date?)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%28e.g.ScopeDocs%2CInvision%29&quot;&gt;&lt;/a&gt;Resources (e.g. Scope Docs, Invision)&lt;/h2&gt;</description>
