Interface PartitionRequestListener

All Known Implementing Classes:
NettyPartitionRequestListener
public interface PartitionRequestListener
When the netty server receives a downstream task's partition request event and finds its upstream task doesn't register its partition yet, the netty server will construct a PartitionRequestListener and notify the listener when the task deploys itself and registers its partition to ResultPartitionManager.
