            <title>[DOCS-14492] Investigate changes in SERVER-56934: Improve collMod API for time-series expireAfterSeconds</title>
                <link>https://jira.mongodb.org/browse/DOCS-14492</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;h2&gt;&lt;a name=&quot;Description&quot;&gt;&lt;/a&gt;Description&lt;/h2&gt;

    &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;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;    For time-series collections, the `expireAfterSeconds` options is now specified as a part of the top-level collection options, rather than being nested inside the `timeseries` subobject. i.e.&lt;/p&gt;

&lt;p&gt;{create: &quot;coll&quot;, timeseries: &lt;/p&gt;
&lt;div class=&quot;error&quot;&gt;&lt;span class=&quot;error&quot;&gt;Unknown macro: {timeField}&lt;/span&gt; &lt;/div&gt;
&lt;p&gt;, expireAfterSeconds: 10}&lt;/p&gt;


&lt;p&gt;When manually creating a time-series buckets collection, the `clusteredIndex` option now takes a boolean, rather than an object. i.e.&lt;/p&gt;

&lt;div class=&quot;error&quot;&gt;&lt;span class=&quot;error&quot;&gt;Unknown macro: {create}&lt;/span&gt; &lt;/div&gt;


&lt;p&gt;When using collMod to change the `expireAfterSeconds` of a time-series collection, `expireAfterSeconds` is now a top-level option and the previous `clusteredIndex` option has been removed. i.e.&lt;/p&gt;

&lt;div class=&quot;error&quot;&gt;&lt;span class=&quot;error&quot;&gt;Unknown macro: {collMod}&lt;/span&gt; &lt;/div&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;    The API for specifying TTL on a time-series collection looks like this:&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;db.createCollection(&apos;ts&apos;, {timeseries: {timeField: &apos;t&apos;, expireAfterSeconds: 3600}}); &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;However, to change the &quot;expireAfterSeconds&quot; value, users have to specify a completely different &quot;clusteredIndex&quot; option:&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;db.runCommand({collMod: &apos;ts&apos;, clusteredIndex: {expireAfterSeconds: 10}}) &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;This is confusing and we should make the API consistent between operations.&lt;/p&gt;


&lt;h2&gt;&lt;a name=&quot;Scopeofchanges&quot;&gt;&lt;/a&gt;Scope of changes&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;ImpacttoOtherDocs&quot;&gt;&lt;/a&gt;Impact to Other Docs&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;MVP%28WorkandDate%29&quot;&gt;&lt;/a&gt;MVP (Work and Date)&lt;/h2&gt;

&lt;h2&gt;&lt;a name=&quot;Resources%28ScopeorDesignDocs%2CInvision%2Cetc.%29&quot;&gt;&lt;/a&gt;Resources (Scope or Design Docs, Invision, etc.)&lt;/h2&gt;
