We kept dealing with GC pauses in go, and eventually after investing a bunch of time trying to fix this - we decided to research what it'd be like to rewrite it in another language. The service itself is pretty simple, so it wasn't a gargantuan task. So it was either, rewrite this again in Go (using off-heap data structures to avoid GC pauses, which makes the software both harder to maintain, and also less idiomatic) or try a new language where we won't have these issues - where we don't have to resort to clever hacks to work around the runtime system. Since then we've continued our investment in Rust, after success of this project (and many others we've yet to blog about as well.)
