BackpressureThe data stream in Rx is emitted from one place to another. The speed at which each place processes data is different. What happens if the producer launches the data faster than the consumer can handle? In a synchronous operation, this is not a problem, for example://produceobservable.create (o, {o.onnext (1 ) O.onnext (2 ) ; O.oncompleted () ; }) Consumeproducer.subscribe (I--{try {thread.sleep (1000 ) System.out .println (
