                    <description>&lt;p&gt;Create time-series buckets collections using the zstd block compressor.&lt;/p&gt;

&lt;p&gt;Use the following &lt;a href=&quot;https://github.com/mongodb/mongo/blob/bcd1f32d78c28f789a88a5c0936cded36abc7386/src/mongo/db/catalog/collection_options.h#L135&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;collection options&lt;/a&gt; config:&lt;/p&gt;

&lt;p/&gt;

			&lt;/td&gt;
		&lt;/tr&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Any user-supplied &lt;tt&gt;storageEngine&lt;/tt&gt; config when creating the collection should take precedence. &lt;/p&gt;</description>
