There is probably 100,000x the actual computer runtime of actual mission critical software running java than Rust. Finance, Medical, Insurance. A huge amount of the actual critical software out there is Java.

Long-running mission-critical stuff has been written in Erlang and running on BEAM since decades now.

Indeed, the correct solution here is emqx

they are java shop, learning/supporting new type of infra adds significant overhead.

Yeah but erlang it’s not the current trendy thing, sadly.

(I’m being ironic of course)

Irony aside, Elixir definitely feels like a current trendy thing, or at the very least more trendy than Java.

And java is???

Who is going to write it?

And who is going to maintain it after the original developer moves on to another project?

the rust cargo cult is real, pun not intended

FWIW I'm a developer working full-time in Rust, advocate for the language, and am on a team of a half-dozen developers working on an (embedded) project in Rust...

And none of us talk this way, nor do most people who work in and like the language that I encounter.

There's always going to be a minority of people who talk this way about tech, doesn't make them representative.

fair enough, fwiw the original cargo cults were not made up of USAF pilots either

Disclaimer: have not tried it myself. I was, however, considering using it to replace Mosquitto as a broker.

Did you have a specific reason to replace mosquitto?

I do not like mosquitto for several reasons, but I never really looked for a replacement (though I wild be happy to find one, and I see that rumqtt is bundled with docker so this could be it)

No specific reasons. Nothing beyond "it was an annoying process to get it set up the way I wanted it"* and "C-language presumed bad; memory-safe-language presumed good".

I did manage to get mosquitto to run according to my liking in a docker container; I can share the steps if anyone is interested -- it was just a long writeup.

Now that mosquitto works and is load bearing for my Home Assistant, I haven't had enough interest in attempting to replace it.

* that is: with a password and without persistence

EDIT: The other one I tried was NATS-with-mqtt-compatibility, but I never got that working the way I expected either.

Or Ada/SPARK.

Your computer must be woefully inadequate for use if you adhere to that principle.
