Comparing the Actor model & CSP concurrency with Elixir & Clojure
summary
Compares BEAM’s Actor model (Elixir) with Clojure’s CSP via core.async, showing per-process heap isolation with independent GC, preemptive VM scheduling and soft real‑time tradeoffs versus JVM shared heap and OS threads. Demonstrates CSP primitives: blocking synchronous channels, buffered, sliding and dropping buffers, and the two core.async runtimes (real JVM threads vs go lightweight tasks), runs 1,000 go tasks to write channels in ~200ms, and discusses Project Loom’s virtual threads as a JVM-level shift.
