This is a performance regression of #27426.
All other queries of this class select rows by their
propertypathanduserid, so the index from #20716 is used. The new query only selects bypropertypath, therefore the old index did not apply.Todo
How to test
Run
EXPLAIN SELECT * FROM `oc_properties` WHERE `propertypath` = 'calendars/admin/inbox';on mariadb/mysql or the equivalent for any other DB before/after applying the optional index. Before no index used. Afterwards it uses an index.
