Minecart - A story of Ruby at a growing company
summary
Square ties Ruby into a Java service ecosystem by diving into JRuby internals and shipping Minecart as a thin adapter layer. It uses protocol buffers for APIs, a custom RPC called sake with a persistent side channel, and Mutual SSL for per-service auth. Result: roughly 50/50 Java vs Ruby services, about 110 services registered, and a hack‑week where a team of three spins up two services and integrates with seven others. The stack reduces duplicated implementations and successfully yields a consistent production story.
