Modifying the Schedule at Runtime
894+
---------------------------------
895+
896+
..versionadded::6.4
897+
898+
Modifying the schedule at runtime and recalculating the heap was introduced in Symfony 6.4.
899+
900+
When a recurring message is added to or removed from the schedule,
901+
the scheduler automatically restarts and recalculates the internal trigger heap.
902+
This allows dynamic control over scheduled tasks during runtime.
903+
code::
904+
905+
// src/Scheduler/DynamicScheduleProvider.php
906+
namespace App\Scheduler;
907+
908+
#[AsSchedule('uptoyou')]
909+
class DynamicScheduleProvider implements ScheduleProviderInterface
910+
{
911+
private ?Schedule $schedule = null;
912+
913+
public function getSchedule(): Schedule
914+
{
915+
return $this->schedule ??= (new Schedule())
916+
->with(
917+
// ...
918+
)
919+
;
920+
}
921+
922+
public function clearAndAddMessages(): void
923+
{
924+
// Clear the current schedule (if any) and add new recurring messages
925+
$this->schedule?->clear();
926+
$this->schedule?->add(
927+
RecurringMessage::cron('@hourly', new DoActionMessage()),
928+
RecurringMessage::cron('@daily', new DoAnotherActionMessage()),
929+
);
930+
