Indeed, and it's also worth noting that doing parallelism in Clojure is inherently easier than in an imperative language since data is immutable by default. If you're using Python or Ruby then you have to consider parallelism up front in your design, meanwhile with Clojure you can just swap
mapwithpmap.Ah, interesting. I'm currently in the Rust rabbit hole, which takes a very different path towards race condition safety (it's imperative and the compiler separately checks that you're not using mutability in parallel contexts), but you actually get quite a similar feature, in that you can swap
.iter().map()with.par_iter().map()(via a library).Yeah, borrow checking approach in Rust is pretty neat since it lets the compiler track exactly where a data structure is being mutated at compile time. Rust approach is more efficient overall as well, but structural sharing has its own benefits as well since you get stuff like history for free. XTDB is a neat project that leverages this property for a temporal db.
