(still updating)
Intro
Supervisor in Elixir (& Erlang) is one of interesting features of language. For legacy use case it's enough, but it's still limited feature for us. Based on process monitoring & linked feature of language (I have explain in this topic) we created a new supervisor for support more common case & more convenience.
Supervisor is target to easy to use, better for multi purposes.
Supervisor's features
In one of supervisor we support:
- Group of processes
- Chain of processes
- Standalone processes
- Support partition for scalable system
Just need one supervisor in application and can add child in application module, config or in runtime (dynamic).
Better for add/remove worker in runtime.
Standalone
This type of process is designed for independent worker, it same with restart strategy :one_for_one in legacy supervisor.
group of processes
For this type of worker, all workers in a same group will have behavior like a sub supervisor. User can send a broadcast message to all workers in group.
chain of processes
For this type, worker will work like a chain with each node is a function that executed in a process. result of worker will be the first argument of next worker.
Chain: worker_1 --result1--> worker_2(result1, ...) --result2--> worker_3(result2,...)
Idea of chain is same with pipe operator but each function was wrapped an run in a different process.
Community
We're working on this library and hope I bring it to community soon!
Some code are ready for PoC, you can found at Github repo
We're welcome Elixir developer join with us to contribute to community!
