@ConsumerType @FunctionalInterface public interface PushEventConsumer<T>
An Async Event Consumer asynchronously receives Data events until it receives either a Close or Error event.

    If ABORT is used as return value, the sender should close the channel all the way to the upstream source.
    static final long
    A 0 indicates that the consumer is willing to receive subsequent events at full speeds.

    • ABORT

      static final long ABORT
      If ABORT is used as return value, the sender should close the channel all the way to the upstream source. The ABORT will not guarantee that no more events are delivered since this is impossible in a concurrent environment. The consumer should accept subsequent events and close/clean up when the Close or Error event is received. Though ABORT has the value -1, any value less than 0 will act as an abort.

    • CONTINUE

      static final long CONTINUE
      A 0 indicates that the consumer is willing to receive subsequent events at full speeds. Any value more than 0 will indicate that the consumer is becoming overloaded and wants a delay of the given milliseconds before the next event is sent. This allows the consumer to pushback the event delivery speed.

    • accept

      long accept(PushEvent<? extends T> event) throws Exception
      Accept an event from a source. Events can be delivered on multiple threads simultaneously. However, Close and Error events are the last events received, no more events must be sent after them.
