Why developers like Project Reactor

What is Project Reactor?

It is a fourth-generation Reactive library for building non-blocking applications on the JVM based on the Reactive Streams Specification. It is a fully non-blocking foundation with efficient demand management. It directly interacts with Java functional API, Completable Future, Stream and Duration.

Project Reactor is a tool in the Java Tools category of a tech stack.

Needs advice

Akka

Project Reactor

and

RxJava

I am working on a project to read data (millions of data) from JMS queue, process the data, and push it to another queue. I am new to Java world, and I have been reading about Spring, Project Reactor, ReactiveRx, etc., for the last couple of days. I am looking for a framework that is easy to use, has less ramp-up time, thread-safety, non-blocking I/O, and less latency. Based on my reading, I am leaning towards ProjectReactor since it has integration with Spring Boot, and it directly interacts with Java functional API, Completable Future, Stream, and Duration. Also, later on, I may have to extend this to read from a different source, so the code should be extensible.

I would like to get thoughts/advice on this.

Project Reactor Alternatives & Comparisons

What are some alternatives to Project Reactor?

RxJava

A library for composing asynchronous and event-based programs by using observable sequences for the Java VM.

Akka

Akka is a toolkit and runtime for building highly concurrent, distributed, and resilient message-driven applications on the JVM.

Spring

A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
