            <title>[DRIVERS-2807] Update GridFS spec for a performant &quot;rename all revisions by filename&quot; feature</title>
                <link>https://jira.mongodb.org/browse/DRIVERS-2807</link>
                <project id="10980" key="DRIVERS">Drivers</project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #fafbfc;border-width: 1px;&quot;&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #fafbfc;&quot;&gt;
&lt;h3&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;&lt;b&gt;Summary&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;The spec doesn&apos;t provide an API to rename every revisions of a filename. The &lt;a href=&quot;https://github.com/mongodb/specifications/blob/master/source/gridfs/gridfs-spec.rst#renaming-stored-files&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;proposed implementation&lt;/a&gt; is inefficient as it requires doing an update_one command for each revision, while it&apos;s more efficient to do an update_many with the filename as criteria.&lt;/p&gt;
&lt;blockquote&gt;&lt;p&gt;To rename multiple revisions of the same filename, users must retrieve the full list of files collection documents for a given filename and execute &#8220;rename&#8221; on each corresponding &#8220;_id&#8221;.&lt;/p&gt;&lt;/blockquote&gt;
&lt;p&gt;The rename by filename API is necessary for &lt;a href=&quot;https://www.php.net/manual/en/streamwrapper.rename.php&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;PHP Stream Wrapper&lt;/a&gt;.&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;&lt;b&gt;Motivation&lt;/b&gt;&lt;/h3&gt;
&lt;h4&gt;&lt;a name=&quot;Whoistheaffectedenduser%3F&quot;&gt;&lt;/a&gt;Who is the affected end user?&lt;/h4&gt;

&lt;p&gt;Applications that use a lot of revisions of the same filename.&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Howdoesthisaffecttheenduser%3F&quot;&gt;&lt;/a&gt;How does this affect the end user?&lt;/h4&gt;

&lt;p&gt;Bad performance scaling when the number of revisions grows&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Howlikelyisitthatthisproblemorusecasewilloccur%3F&quot;&gt;&lt;/a&gt;How likely is it that this problem or use case will occur?&lt;/h4&gt;

&lt;p&gt;Edge case, maybe an incorrect usage of GridFS.&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Iftheproblemdoesoccur%2Cwhataretheconsequencesandhowseverearethey%3F&quot;&gt;&lt;/a&gt;If the problem does occur, what are the consequences and how severe are they?&lt;/h4&gt;

&lt;p&gt;Degraded performances&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisissueurgent%3F&quot;&gt;&lt;/a&gt;Is this issue urgent?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;No&lt;/em&gt;&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisticketrequiredbyadownstreamteam%3F&quot;&gt;&lt;/a&gt;Is this ticket required by a downstream team?&lt;/h4&gt;

&lt;p&gt;PHPLIB implementation of GridFS stream wrapper&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Isthisticketonlyfortests%3F&quot;&gt;&lt;/a&gt;Is this ticket only for tests?&lt;/h4&gt;

&lt;p&gt;&lt;em&gt;No&lt;/em&gt;&lt;/p&gt;
&lt;h3&gt;&lt;a name=&quot;AcceptanceCriteria&quot;&gt;&lt;/a&gt;&lt;b&gt;Acceptance Criteria&lt;/b&gt;&lt;/h3&gt;

&lt;p&gt;Update the spec to give a performant way to rename all revisions of a filename&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;</description>
