Leveraging Rust in our high-performance Java database

Yeah, sounds like a lot of effort.

The only thing they say that explains it is they end up with a single jar file, whose only dependency is the JRE.

So I guess they get platform independence and easy installation.

Keep in mind the JNI libs are platform specific. That means available platforms are a function of what the JRE runs on AND they have built the shared lib for (and bundled in to the jar)

QuestDB engineer here: We use jlink to create images for selected platforms. This means not even JRE is a dependency: You unpack a tarball and you are good to go. See: https://questdb.io/docs/get-started/binaries/

Well, technically it is a dependency in that you can't target platforms there isn't a JRE for. But I take your point about simplifying installation.
