            <title>[DOCS-8117] Deprecate single document aggregation result option</title>
                <link>https://jira.mongodb.org/browse/DOCS-8117</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Prior to MongoDB 2.6, aggregation (without a $out stage) would return results as a single document. With MongoDB 2.6 we introduced a cursor-based interface and made this the default in both shell and drivers. &lt;/p&gt;

&lt;p&gt;In 3.4 use of the not-cursor-based option is being deprecated&lt;/p&gt;</description>

If the results fit inside a single 16MB BSONObj, then they can also be returned inside a single batch. In this case, no extra round-trip is required. If the results would not fit inside a single 16MB BSONObj, then aggregation cursors are required anyway. In addition, the client-side API for iterating the result set should be cleaner when using agg cursors.&lt;/p&gt;</comment>
