            <title>[SERVER-84333] Prevent a blocking sort from consuming all available disk space</title>
                <link>https://jira.mongodb.org/browse/SERVER-84333</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;With allowDiskUseByDefault defaulting to true from v6.0 onwards,have we or would we consider putting any guardrails in place to limit the size that an external sorting file can grow to, the idea being a runaway query would not be able to take down a node by exhausting all available disk space? &lt;/p&gt;</description>

                            <comment id="5962943" author="kyle.suarez" created="Wed, 20 Dec 2023 14:49:55 +0000"  >&lt;p&gt;Per a discussion with &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=ilan.cohen%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;ilan.cohen@mongodb.com&quot;&gt;ilan.cohen@mongodb.com&lt;/a&gt; and &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=ronan.merrick%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;ronan.merrick@mongodb.com&quot;&gt;ronan.merrick@mongodb.com&lt;/a&gt; on a linked ticket, it seems that we offer the possibility to limit the RAM used via a query knob but not the size of the data spilled. The server &lt;a href=&quot;https://github.com/mongodb/mongo/blob/08da07a44f161379557a7dece2eb330749b9dc28/src/mongo/db/sorter/sorter.cpp#L1451C7-L1454&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;does detect when it&apos;s out of disk space but only when it&apos;s too late&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Sending this to the Query Execution team for triage consideration.&lt;/p&gt;</comment>
