Kafka libraries outside Java (and maybe Go) are such a disaster. I remember getting paged because all my NodeJS Kafka consumers were crashlooping from a segfault in Confluent's official Javascript client (wrapper around rdkafka C++). Why? Because Confluent changed some sort of telemetry setting on the broker. I also get segfaults in Rust using the most popular client out there (also an rdkafka wrapper) without any `unsafe` (although there were threads).
