Queueing broadcast events is incredibly important, especially at scale. Unfortunately at the moment there is no out-of-the-box method to prevent queues from being overloaded with repeated events. This can lead to redundant broadcast events that eat up data allowances.
I'm proposing a new
Illuminate\Contracts\Broadcasting\ShouldBeUnique
contract that tells the dispatcher to use a separateUniqueBroadcastEvent
class. If nouniqueId
method or property is defined, the event's class name is used as the identifier. You can also setuniqueFor
anduniqueVia
like other unique queue jobs via a property or method.
