Comment:

 In [changeset:"34217"]:
 {{{
 #!CommitTicketReference repository="" revision="34217"
 Omit the `ORDER BY` clause when updating object term cache.

 The `ORDER BY` clause was forcing filesorts on large tables, and is
 unnecessary, since term order doesn't matter when updating the cache.

 Props mbrandys, wonderboymusic.
 Fixes #28922.
