In my 8.5 years of Elixir practice I found it much easier to just use a Rust NIF or, in extreme cases, publish to an external job queue. Had success with one of Golang's popular ones (River); you schedule stuff for its workers to do their thing and they publish results to Kafka. Was slightly involved but IMO much easier than trying to coax Golang / Java / C++ / Rust nodes join a BEAM cluster. Though I am also negatively biased against horizontal scaling (distribution / clusters) so there's also that.
