Stability and safety are the least of the concerns in data processing and database workloads. That's totally not the reason why we saw an increase of these systems during the 90s and early 00s written in Java or similar alternative languages. It was ease of use, low-entry bar into the ecosystem and generally developer pool accessibility. Otherwise, the cost is the main driver in infrastructure type of software and the reason why we see many of these rewritten exactly in C++. Rust is just another contender here, and it's usually because of the performance and a lot of hype recently, which is fair.
