            <title>[SERVER-13411] parallelCollectionScan does not provide a time limit option (maxTimeMS).</title>
                <link>https://jira.mongodb.org/browse/SERVER-13411</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Testing with the new parallelCollectionScan command and it looks like this command does not support the ability to limit the execution time of the operation.&lt;/p&gt;

&lt;p&gt;I had expected it to work like the normal query operation were the cursor has a time limit associated with it that once exhausted causes a failure back to the client.&lt;/p&gt;

&lt;p&gt;Is there a reason this functionality was left out?&lt;/p&gt;

&lt;p&gt;I think all that would be needed would be to call setLeftoverMaxTimeMicros() based on a maxTimeMS within the command on the ClientCursor created on line 238 of parallel_collection_scan.cpp. &lt;a href=&quot;https://github.com/mongodb/mongo/blob/master/src/mongo/db/commands/parallel_collection_scan.cpp#L238&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo/blob/master/src/mongo/db/commands/parallel_collection_scan.cpp#L238&lt;/a&gt;&lt;/p&gt;</description>
