// Simulate a data source emitting a continuous stream of data at a high rate
Flux<Integer> dataSource = Flux.range(1, Integer.MAX_VALUE);
  
// Process the data with back pressure using limitRate operator
dataSource
  .limitRate(10) // Control the number of elements emitted per request (back pressure)
  .doOnNext(data -> { // Simulate processing delay
    try {
      Thread.sleep(100);
    }
    catch (InterruptedException e) {
      e.printStackTrace();
    }
    System.out.println("Processed: " + data);
  })
  .subscribe();

Açıklaması şöyle

In this example, the Flux.range(1, Integer.MAX_VALUE) simulates a continuous stream of data. The limitRate(10) operator specifies that the data processing should be limited to 10 elements per request, effectively controlling the back pressure.

As a result, you’ll notice that the data processing rate is limited, and the doOnNext method will print  "Processed: <data>" with a slight delay between each processed element
