            <title>[SERVER-76026] Limit memory usage for bulkWrite (mongod)</title>
                <link>https://jira.mongodb.org/browse/SERVER-76026</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;On mongod, bulkWrite &lt;a href=&quot;https://github.com/10gen/mongo/blob/c6e5701933a98b4fe91c2409c212fcce2d3d34f0/src/mongo/db/commands/bulk_write.cpp#L709-L710&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;uses &lt;tt&gt;WorkingSet&lt;/tt&gt; and &lt;tt&gt;QueuedDataStage&lt;/tt&gt; to queue data&lt;/a&gt; and construct cursor response. Memory usage for &lt;tt&gt;WorkingSet&lt;/tt&gt; and &lt;tt&gt;QueuedDataStage&lt;/tt&gt; is unbounded. And they currently do not support spilling to disk. Additionally, we currently build the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c6e5701933a98b4fe91c2409c212fcce2d3d34f0/src/mongo/db/commands/bulk_write.cpp#L648-L649&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;entire response&lt;/a&gt; in memory first without a limit.&lt;/p&gt;

&lt;p&gt;This ticket is to limit the memory usage (e.g. capped at 100MB) for bulkWrite by putting a cap for the size of responses queued.&lt;/p&gt;

&lt;p&gt;The end goal is to limit the memory usage when we build or cache responses for bulkWrite ops. Once this limit is hit, we should stop executing the remaining operations in this bulkWrite.&lt;/p&gt;</description>
