(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
