Into Production
summary
Uses Elixir in production for ~2½ years to build a game backend platform with binary routers, Ecto-backed Postgres sharding and a message gateway; creates releases with relx/exm instead of deploying source; ships a small migrator tool to run migrations against many schemas; scales beyond the ~100–150 fully‑meshed limit with hidden nodes and a partial mesh over 128 shards and router catalogs; debugs bottlenecks with Observer (reductions and message queues), fixes protocol consolidation, and tunes VM args (+K, kernel_poll) and one VM per machine.
