Google Workflow/TaskMaster equivalent

[spaskob]

This was a very simple and powerful framework for building continuous pipelines at Google. I am not able to find anything remotely close to it. Any suggestions?

A few years ago I started a quick&dirty tool (https://github.com/mkmik/masstasker) that is inspired by TaskMaster and I recently updated it to handle some practical workloads I have at $dayjob.

It's not a full reimpl (also because I don't really remember much of the details, certainly not the impl itself) but it's inspired by my memories of what I liked about it:

1. immutable tasks
2. protobufs for user-defined task bodies
3. simple gRPC API you can manually use to operate on tasks
4. lightweight and simple to setup
5. not too high level, not too low level
