Persistent Collection VS kitteh

So does Java! Also, kotlinx.collections is still not stable and I don't think they are intending to make it so any time soon.

I actually prefer pcollections: https://github.com/hrldcpr/pcollections

AtomicReference + immutable data types is a really nice way to program in Java, and is basically the way most Clojure programs are written.

You might consider persistent collections instead of immutable collections, I believe it is more optimized https://github.com/hrldcpr/pcollections

Alternatively, you could check some micro http server, many just require a couple of lines to setup. I've even made one myself, kitteh, otherwise there plenty to choose from, spark for example is super simple.

uhm i'll look into it when it's ready, then decide if use it on my small web server. Probably more for exploration and fun then for real need.

Spring boot is ok, altho i feel it only spread becouse of "spring". Small self contained http servers library existed before (they're pretty simple to make too, i did one myself), they were just not considered, in favour of big servers like tomcat etc.
