The libraries offer a range of operators for all kinds of functions. Each of the operators accomplishes its tasks similarly to that of a workstation on an assembly line. It takes input from the previous workstation and provides input to the next workstation. These operators offer all kinds of data transformation, stream orchestration, and error handlers.
ReactiveX makes its easier to build event-based applications. However, the framework does not present the ways in which different event-driven applications should interact with each other. In a microservice architecture consisting of numerous event-driven services, the gains made are often offset by the workarounds required for inter-process communication.
