Introduction

This is a sample Lagom/Java application that has a Customer service that allows you, via REST, to:

1. Add a customer
2. Get a customer
3. List customers (via read-side view)
4. Disable a customer (acting as a soft delete)

This implementation uses Cassandra for both the write-side and read-side.
