            <title>[SERVER-11828] Tag ranges for embedded shard keys</title>
                <link>https://jira.mongodb.org/browse/SERVER-11828</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;While it is possible to use an embedded field as a shard key, it is not possible to define tag ranges for such a key.&lt;/p&gt;

&lt;p&gt;For example, I have set up the field &quot;_id.ts&quot;, a timestamp, as a shard key, but defining a tag range for it&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;sh.addTagRange (&quot;ncdc.data&quot;, { &quot;_id.ts&quot; : MinKey }, { &quot;_id.ts&quot; : ISODate(&quot;2012-12-01T00:00:00&quot;) }, &quot;archive&quot; )&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;results in the error &quot;can&apos;t have . in field names &lt;span class=&quot;error&quot;&gt;&amp;#91;_id.ts&amp;#93;&lt;/span&gt; at src/mongo/shell/collection.js:145&quot;. This is probably an implicit restriction due to the way tag ranges are specified, but it is still unfortunate and should be possible.&lt;/p&gt;</description>
