Finagle Under the Hood
Dive deep into the internals of Finagle, an extensible RPC system for JVM written in Scala, in this 46-minute talk from Scala Days New York 2016. Explore the complex logic behind Finagle's programming model, where servers and clients are viewed as easily composable functions. Discover the inner workings of connection pooling, load balancing, and circuit breaking. Follow along as the speaker walks through each module, explaining what happens when sending a request to a Finagle client and receiving a request by a Finagle server. Learn about server concurrency limits, request timeouts, client response classification, retries, retry budgets, backoff strategies, and load balancing techniques. Gain insights into circuit breaking, failure accrual, and other advanced features that make Finagle a powerful tool for building distributed systems.
