            <title>[DOCS-5078] Concurrency FAQ for 3.0 is not up-to-date on locking in 3.0</title>
                <link>https://jira.mongodb.org/browse/DOCS-5078</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;In these sections of the concurrency FAQ:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/faq/concurrency/#what-type-of-locking-does-mongodb-use&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/faq/concurrency/#what-type-of-locking-does-mongodb-use&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;http://docs.mongodb.org/manual/faq/concurrency/#how-granular-are-locks-in-mongodb&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://docs.mongodb.org/manual/faq/concurrency/#how-granular-are-locks-in-mongodb&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;The information is not up to date on locking with 3.0 and WiredTiger, since mmapv1 now offers collection-level locking and WiredTiger offers document-level locking. It&apos;s vexing because this FAQ is where we point community members with basic questions about concurrency like &quot;can I write to collection x and y at the same time in 3.0?&quot;&lt;/p&gt;

&lt;p&gt;(Pardon if this is a duplicate- seems like it should&apos;ve been picked up by now but a search didn&apos;t turn it up)&lt;/p&gt;</description>
