What are Reactive Streams?

Reactive Streams is a standard specification designed to provide asynchronous, non-blocking, and backpressure-enabled data stream processing. It defines a set of interfaces and rules for building and handling reactive data streams in a consistent manner, allowing for the interoperability of different implementations (like Akka Streams, Project Reactor, and RxJava).

Key Goals of Reactive Streams :
  1. Asynchronous and Non-blocking: Enable systems to handle data streams asynchronously without blocking threads, ensuring efficient use of system resources.
  2. Backpressure: Prevent faster producers from overwhelming slower consumers by providing a mechanism to manage the flow of data.
  3. Interoperability: Provide a standard interface so different libraries and tools can work together seamlessly.
  4. Scalability: Support systems that can scale effectively for both high and low-throughput scenarios.
