If you’ve convinced yourself you need to perform an async call in Erlang, you can use some of the functions in the rpc module.
The most immediately useful function in that module that helps is async_call:
async_call(Node, Module, Function, Args) -> Key
You can then call yield on the key to obtain the data:
yield(Key) -> Res | {badrpc, Reason}.
