Description

I've talked to a few users who keep their scheduled tasks in a database and want to use scheduler to run them. This is not easily possible now as the schedules are set when first running messenger:consume scheduler_default.

Within the current scheduler architecture, what would be required to achieve this? I'm don't have a great understanding of the deep scheduler internals (the trigger heap system).

Example

class MySchedule implements ScheduleProviderInterface
{
    public function getSchedule(): Schedule
    {
        $schedule = new Schedule();

        // fetch tasks from db and add to schedule as recurring messages

        return $schedule;
    }
}
