Creating concurrent and parallel emissions

Besides multithreading, it is possible to achieve concurrency and parallelism with Reactor Core. This recipe is still about Scheduler but in parallel mode. The clear concept of parallelism is all about having these n operations distributed to m workers that are executed independently of each other. This recipe will utilize Schedulers to enable parallelism in Reactive Streams.

Getting ready

Open project ch07 again and add the following service that shows different ways of how to implement concurrent and parallel Streams using Schedulers and some Reactive Core 3.x operators.

How to do it...

To implement concurrent and parallel Stream emissions, perform the following steps:

1. Add the following service class in our org.packt.reactive.code.service package. This class contains method templates that will detail parallelism and concurrency based on Reactive Streams specification:

public interface EmployeeParallelStreamservice { 
    
   public Flux<String&gt...
