TL:DR - Use Rust instead of C++ to write native Node.js modules!

RisingStack faced a shocking event last year: we reached the maximum speed that Node.js had to offer at the time, while our server costs went over the roof. To increase the performance of our application (and decrease our costs), we decided to completely rewrite it, and migrate our system to a different infrastructure - which was a lot of work, needless to say.

I figured out later that we could have just implemented a native module instead!

Back then, we weren’t aware that there was a better method to solve our performance issue. Just a few weeks ago I found out that another option could have been available.
