Capital One's experience with building a Reactive System with Akka

Sign up or log in to save this to your schedule and see who's attending!

A newly assembled team. No reactive programming experience. A deadline that cannot be missed. In this session, we will describe the experience of learning reactive programming and using it to build an API for a credit card fulfillment process. Tight timelines and dependent system constraints increased the challenge of implementation. The team chose to implement the solution with Akka, Lagom and persistence using PostgreSQL. We will discuss the patterns and techniques leveraged including the promise pattern, Akka Clustering, Java Futures, and Error Handling / State Management. We will also demonstrate the challenges faced with upstream/downstream TPS constraint and resolution provided with Scheduler & Config driven Throttling Mechanism. We will review the options considered, learnings through this journey and what lies ahead for the service.
