Flux is the framework I've been meaning to release for a very long time .
What's it good for? Message queues; organizing your data processing scripts in a scalable way; de-coupling your processing pipeline elements, making them reusable and testable; seeing your system as a collection of lego-like blocks which can be combined and replaced as you like. With Flux, your code is a series of tubes.
Flux is a rewrite of Stream framework which we wrote and used in Yandex for many years. Stream:: namespace on CPAN is taken, though, which gave me the reason to do a cleanup before uploading it, as well as a chance to rewrite everything with Moo/Moose.
I'm planning to release Flux in small chunks, explaining them along the way in separate blog posts, as time will allow. Today, I'll explain the main ideas behind it, some core classes, and how all its parts are working together.
