            <title>[JAVA-2097] Support for new 3.2 $filter(aggregation)</title>
                <link>https://jira.mongodb.org/browse/JAVA-2097</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;Hi Guys,&lt;/p&gt;

&lt;p&gt;I found in documentation for 3.2 version new amazing feature &lt;a href=&quot;https://docs.mongodb.org/manual/reference/operator/aggregation/filter/#exp._S_filter&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;$filter(aggregation)&lt;/a&gt; which significant improve performance of array filtering. Unfortunately, I couldn&apos;t found java API for this feature usage.&lt;/p&gt;

&lt;p&gt;Could you provide details when this feature will come to java driver? Also I will grateful if you provide some workaround how to use this feature with current driver.&lt;/p&gt;</description>

&lt;p&gt;Thanks, I&apos;m seeing. I&apos;ll make my own builder, but anyway are you planning implement this method?&lt;/p&gt;</comment>
