AggregateCommandDispatcher

class AggregateCommandDispatcher<C : Any, S : Any>(val aggregateMetadata: AggregateMetadata<C, S>, val parallelism: Int = MessageParallelism.DEFAULT_PARALLELISM, val scheduler: Scheduler, val messageFlux: Flux<ServerCommandExchange<*>>, val name: String = "-", aggregateProcessorFactory: AggregateProcessorFactory, commandHandler: CommandHandler, serviceProvider: ServiceProvider) : AggregateMessageDispatcher<ServerCommandExchange<*>>

Aggregate Command Dispatcher Grouped by NamedAggregate.

----

One AggregateId binds one Worker(Thread). One Worker can be bound by multiple aggregateIds. Workers have aggregate ID affinity.
