Just checking this theoretically changes current behaviour. On the other hand, at the moment, I think it is always true for `ANY` where we check it if `ScheduleMode.LAZY_FROM_SOURCES`. I am also not sure that `ALL` config makes sense together with `ScheduleMode.EAGER`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
