Why Is Jepsen Written in Clojure?
Nope! For a few reasons Jepsen sticks very closely to Traditional JVM Threads.
Part of that is because Jepsen isn't hyper-concurrent. Most concurrency errors manifest in just a handful of client threads, and the JVM will run ~10K threads without too many issues.
Another part is that I spend a lot of time debugging and profiling. Core.async turns stacktraces into Swiss cheese--it has to, to perform its implicit continuation-passing magic. But that can make it really hard to figure out Who Called What When, and Why Is This Process Slow. Standard blocking IO calls are also something that my profiler (YourKit) can analyze well.
Finally, I invest a lot of time into tuning Jepsen for speed, and manage the handoff of data between threads carefully. In a system where actors were handing off state constantly core.async would be a bigger help, but there's really only a couple shapes for concurrent handoff in Jepsen, and they're addressed by either j.u.c. queues, forkjoin-style structured concurrency, or Weird Transactional Threadpool stuff.
For a little more on this, take a look at https://github.com/aphyr/dom-top or https://github.com/jepsen-io/history/blob/main/src/jepsen/hi...
