demo-akka-persistence-postgres

This is a small demo project on how to configure your application to use akka-persistence-postgres.

It shows the following:

How to configure akka-persistence-postgres,
How to connect to a Postgres database,
The postgres database schema to use,
How to persist events to the journal,
How to create, configure and use Google Protocol Buffers for your data model,
How to create, configure and an EventAdapter, to tag events, and convert your domain model to your data model (protobuf),
How to create, configure and use Custom Serializers to convert your data model (protobuf) to byte arrays and vice-versa,
How to query for events using the akka-persistence-query interface,
How to query tagged events using the akka-persistence-query interface,
How to create your own custom persistency strategy using a custom journal dao using three tables, one event-log and two event-content tables for storing event data typed (that is query-able, I would not recommend this strategy though, but its possible!),
In short, how easy it is to create an event sourced application.

Have fun!

To run the examples you have launch the local PostgreSQL instance:

./launch-postgres.sh
