So, you use the local event bus only if you an event should always remain in-process in any scenario. For other type of events, use the distributed event bus.

Technical Differences

There are some technical differences between the local and distributed event bus:

• You can send entities or other non-serializable objects using the local event bus since these objects are not serialized/deserialized on event publishing. On the other hand, distributed event bus serializes/deserializes objects once you use a real distributed event bus provider.
• The local event bus is always transactional in the database level. For distributed event bus, you should enable inbox/outbox pattern to ensure data consistency once you use a real distributed event bus provider.

These differences are because of the distributed event bus supports distributed scenarios while the local event bus is only used for in-process messaging. When you don't set up a real distributed event bus provider, these differences are not valid.
