GenStage and Flow resources?
I have been hearing about GenStage and Flow, a tool built upon it, for quite some time. I understand it allows us to program in a paradigm that uses stages and flows and has back-pressure included.
However I have a few issues when it comes to adopting them (or even considering it).
There is only the documentation
That’s it. Documentation alone is not enough for me, I don’t learn how to use a technology by simply glossing over the docs. It’s like learning Java by reading only the JavaDocs. Sure someone will be able to do it. I am not that someone. I am dumb as a brick 
Conferences
You may say there are some conferences, but they are completely biased towards using GenStage or Flow and how great they are. I want the complete picture. I want to know when it is a good idea to use it and when it’s not. Like Agents. I know when to use them and when not to use them.
Books
In all the books I have seen, there are no GenState chapters. Only GenServer. I get it that GenServer is a major building block, but when none of the books out there has a chapter about it, it really makes me wonder if we need GenStage at all.
Even today I asked about GenStage to @ElixirCasts and they didn’t reply - it makes me think this is not an interesting topic at all.
Do you guy know of any unbiased GenStage books or resources?

Flow isn’t a successor, it’s a tool built on top of the primitives of GenStage. It says so at the top of the repository.
Did this actually need to be a new thread off of your process-mailbox post?

I don’t think you can compare coverage of GenServer and GenStage. One is a integral part of the language’s stdlib, while the other is a third-party package, which happens to be quite good for processing pipelines. It’s a common, but certainly not universal problem to face.

I only know of the talks
btw José is announcing Broadway tmrw

The chapter 5 (Demand-Driven Processing) of this book is a good example.

Fixed.
Yes. I don’t want GenStage and Flow to hijack the other thread. I want as many ideas as possible there, specially those not including GenStage or Flow. Placing this there would just obscure good resources in a thread that doesn’t even mention GenStage nor Flow in the title.
If it is that much common, than we should have books and resources about it. Phoenix is a framework, a 3rd party tool to Elixir that happens to be good for web projects, but you have a ton of books about it.
Me too =(

So, Flow will be obsolete now? Do are they meant to solve different problems within the real of pipelined workflows ?
Will have a look!
