            <title>[JAVA-1571] Handle asynchronous aggregate/mapreduce to a collection</title>

                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;There is currently a race condition because the aggregate/mapreduce is asynchronously executed but then a MongoIterable on the collection the results are being written to is returned immediately&lt;/p&gt;</description>

Otherwise there is no way for the user to know when a $out aggregation completed except by starting to iterate through the results.&lt;/p&gt;</comment>
