 Consumer consumer)

Checks if the given consumer is compatible with the given dispatcher. They are incompatible if

• the subscription type of the consumer differs from the subscription type of the dispatcher or
• if both the consumer and dispatcher are of CommandSubscribe.SubType.Key_Shared type but their policies differ (KeySharedMode.AUTO_SPLIT/ KeySharedMode.STICKY or allowOutOfOrderDelivery true/false).

Parameters:

dispatcher - The dispatcher of the subscription

consumer - New consumer to be added to the subscription

Returns:

Optional containing failed future with BrokerServiceException.SubscriptionBusyException if consumer and dispatcher are incompatible or empty optional otherwise.
