Finagle Your Application to Prevent Outages, Using Twitter's Finagle

Many Web pages today rely on Web services that use various protocols. A failure or delay of a service should not cause your page to fail. Finagle, which is built on top of Netty, can build clients and servers in Java, Scala, or any other JVM language. Future objects are used to register a computation that hasn't yet completed and may not succeed. Service objects transform requests into future responses. Filter objects can be used to decouple the protocol from the request and handle exceptions, authorizations, and other events. Codec objects can be used to encode and decode various protocols. Servers include service and filter objects. Finagle clients easily implement connection pooling, load balancing, logging, and statistics reporting. Learn more in this session.
