Lagom is an open source framework for building reactive microservice systems in Java or Scala.
This repository contains code examples to help you understand how to achieve common goals. In general, code in each folder of this repository tries to answer a question of type "How do I xyz ?". For example: "How do I use RDBMS read-sides with Cassandra write-sides?".
