                            <comment id="1566171" author="rassi@10gen.com" created="Sat, 6 May 2017 00:31:44 +0000"  >&lt;p&gt;No C driver changes are needed.  The &lt;a href=&quot;http://mongoc.org/libmongoc/current/mongoc_collection_aggregate.html&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;documentation for mongoc_collection_aggregate()&lt;/a&gt; indicates that it supports passing through any &quot;[parameter] to the aggregate command, besides pipeline, as fields in opts&quot;.&lt;/p&gt;

&lt;p&gt;Thus, the work for this ticket should be:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;API changes: add options::aggregate::hint() getter and setter.&lt;/li&gt;
	&lt;li&gt;Implementation changes: serialize the hint to the options document in collection::aggregate().&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;The driver already has &quot;support for index hints against non-materialized views, for all operations that support hint.&quot;, so no changes are needed for views.&lt;/p&gt;</comment>
