      Description

      there is a large performance cost to this.

      The old impl for this type of thing, QueryFilter, recommends :

      @deprecated use a CachingWrapperFilter with QueryWrapperFilter

      The deprecated QueryFilter itself also suffers from the problem because its now implemented using a CachingWrapperFilter and QueryWrapperFilter.
