Non-Java workers?

I would like to know what are the way to have process step processed by something else than Java ?

I am investigating on various workflow management system, and I’m basically looking for something like that Zeebe give, which is the possibility for workers to register for task processing (using gRPC for this case).
What would be the equivalent here ? (In our case we would need to use Python and Go for example),
So far it looks like we can use the subprocess approach but I think it’s not very optimal from a performance point of view VS a pub-sub model


I’m not aware of any no/low code solution to have external processes register to complete tasks. It should, however, be fairly easy to call a gRPC method using a delegate in a service task.
