Configuration

• How to configure the data store (mysql/postgress/mongo...) ?
  • A: Looks like this is the class implementing Broadway\EventStore\EventStoreInterface. This can ben a DBALEventStore (with the problems explained below) or an InMemoryEventStore which doesn't have any dependencies, aka for testing purposes.
• How to setup Elasticsearch as read model ?

Event Store

About the Broadway\EventStore\EventStoreInterface, there is a DBALEventStore, which uses Doctrine DBAL, but has more dependencies:

• Doctrine\DBAL\Connection $connection
• Broadway\Serializer\SerializerInterface $payloadSerializer
• Broadway\Serializer\SerializerInterface $metadataSerializer
• $tableName

Using Laravel-Doctrine package, how can we get these requirements? The DBAL connection has been instantiated but don't know what the 2 SerializerInterface dependencies are.
