Distributing systems in Scala with Fiangle

on YouTube ↗30m

" summary

Finagle on Netty is an RPC framework for the JVM that Twitter uses to run 100+ services handling hundreds of thousands of requests per second; examples show building an HTTP proxy in a few lines, composing Futures-as-mystery-box callbacks and filters-as-middleware, and returning immediate or backend-wrapped futures. Production features include connection pooling, load balancing with health-driven eviction, ZooKeeper service discovery, JSON metrics on an admin port (p50/p75/p99), and these components work in live deployments.
