> Rust is rather heavy on its copy/clone imposed semantics making it potentially less suitable for low-latency or large data volume processing workloads. Picking Rust for its performance potential only means that you're going to have a harder time beating other native performance-oriented stream processing engines written in either C or C++, if that is your goal of course.
There is absolutely nothing in Rust's semantics preventing you from writing high-performance data processing workloads in it, and in fact it's one of the best languages for that purpose. Beyond that, the usual barrier to entry for working on a product like this written in C++ is incredibly high in part because stability and safety are so critical for these products--which is one of the reasons that in practice they are often written in memory safe languages, where C++ is not even an option. Have you worked on any nontrivial Rust data processing product where "copy/clone imposed semantics" somehow prevented you from getting big performance wins? I'd be very curious to hear about this if so.
