      Summary

      The spec doesn't provide an API to rename every revisions of a filename. The proposed implementation is inefficient as it requires doing an update_one command for each revision, while it's more efficient to do an update_many with the filename as criteria.

      To rename multiple revisions of the same filename, users must retrieve the full list of files collection documents for a given filename and execute “rename” on each corresponding “_id”.

      The rename by filename API is necessary for PHP Stream Wrapper.

      Motivation

      Who is the affected end user?

      Applications that use a lot of revisions of the same filename.

      How does this affect the end user?

      Bad performance scaling when the number of revisions grows

      How likely is it that this problem or use case will occur?

      Edge case, maybe an incorrect usage of GridFS.

      If the problem does occur, what are the consequences and how severe are they?

      Degraded performances

      Is this issue urgent?

      No

      Is this ticket required by a downstream team?

      PHPLIB implementation of GridFS stream wrapper

      Is this ticket only for tests?

      No

      Acceptance Criteria

      Update the spec to give a performant way to rename all revisions of a filename
