            <title>[SERVER-24658] Is it possible to control the resources allocated for aggregation ?</title>
                <link>https://jira.mongodb.org/browse/SERVER-24658</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;I am working on a project with around 2m record. I use aggregation framework to manipulate the whole collection to generate a report. This aggregation query takes a while, but I don&apos;t want to block the db from serving requests from normal users. I don&apos;t mind if the generation process takes longer, so may I know if it is possible to just allocate certain system resources for one aggregation query which is supposed to take a long time ?&lt;/p&gt;</description>

                            <comment id="1299505" author="ramon.fernandez" created="Mon, 20 Jun 2016 12:38:06 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=witmoyl&quot; class=&quot;user-hover&quot; rel=&quot;witmoyl&quot;&gt;witmoyl&lt;/a&gt;, there&apos;s currently no facility to limit resources for aggregation operations, but those should not block other users or operations. If you&apos;re concerned about performance impact you may want to consider using a replica set and run your aggregation report on a secondary node.&lt;/p&gt;
