Project Reactor

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.
