Event store

Broadway provides several event store implementations. By default the InMemoryEventStore is used.

There a several optional persisting event store implementations:

• broadway/event-store-dbal using Doctrine DBAL
• broadway/event-store-mongodb using MongoDB

These can be very easily installed using Symfony Flex.

Custom event store

You can also create your own event store implementation by implementing the EventStore interface.

Next, create a service definition for it:

# services.yaml
my_event_store:
    class: MyEventStore

And configure it in the bundle config:

# config.yaml
broadway:
  # a service definition id implementing Broadway\EventStore\EventStore,
  event_store: "my_event_store"
