            <title>[SERVER-2920] add atomic output collection to DBQuery</title>
                <link>https://jira.mongodb.org/browse/SERVER-2920</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;A Map/Reduce query can atomically output its results to a separate collection, which is nice for a job where you want to create &quot;views&quot; of the data that you can then query within.&lt;/p&gt;

&lt;p&gt;It would be nice if immediate queries could do the same thing, eg.&lt;/p&gt;

&lt;p&gt;db.mycollection.find(&lt;/p&gt;
{hasAttachments:true}
&lt;p&gt;).out(attachcollection);&lt;/p&gt;

&lt;p&gt;It could operate asynchronously, and attachcollection would remain unmodified until the query was complete after which it would be atomically swapped with the temporary collection in which the new results reside.&lt;/p&gt;</description>
