Eventuate Examples Java Spring Todo List

An Eventuate project

This project is part of [Eventuate](http://eventuate.io), which is a microservices collaboration platform.

Todo List example application

The Todo List application is the hello world application for the [Eventuate™ event sourcing](http://eventuate.io). It illustrates how you can use the platform to write an application with a [microservices architecture](http://microservices.io/patterns/microservices.html) that uses [Event Sourcing](http://microservices.io/patterns/data/event-sourcing.html) and [Command Query Responsibility Segregation (CQRS)](http://microservices.io/patterns/data/cqrs.html). The Todo List application lets users maintain a todo list.

The Todo List application is a Java and Spring Boot application built using Eventuate™'s Event Sourcing based programming model. Todos are implemented by an Event Sourcing-based `TodoAggregate`. The aggregate's events are persisted in the Eventuate event store. The application also maintains a materialized view of the data in MySQL.

Architecture

The Todo application has a microservice architecture. It is written using the [Eventuate Client Framework for Java](http://eventuate.io/docs/java/eventuate-client-framework-for-java.html), which provides an [event sourcing based programming model](http://eventuate.io/whyeventsourcing.html). The following diagram shows the Todo List application architecture:
