            <title>[DOCS-15129] [Server] Investigate changes in SERVER-63841: Disable metric indexes on 5.3</title>
                <link>https://jira.mongodb.org/browse/DOCS-15129</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>    &lt;div class=&quot;panel&quot; style=&quot;background-color: #c2d2c2;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 1px;background-color: #239eb0;&quot;&gt;&lt;b&gt;Original Downstream Change Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #c2d2c2;&quot;&gt;
&lt;p&gt;    Any 5.3 features from PM-2189 or PM-2232 that we documented, will not be in 5.3 after all.  This includes:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;Changes to createIndex on time-series collections.&lt;/li&gt;
	&lt;li&gt;Changes to $geoNear.&lt;/li&gt;
	&lt;li&gt;Changes to partial indexes.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Some or all of these features may come out in 6.0, or a later version.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;
&lt;h2&gt;&lt;a name=&quot;DescriptionofLinkedTicket&quot;&gt;&lt;/a&gt;Description of Linked Ticket&lt;/h2&gt;
&lt;p&gt;    Our initial performance tests for this feature (indexes on metric fields, for time-series) show that it can actually hurt performance in many cases, so we should disable it until we can better understand the problem and improve it.&lt;/p&gt;
