AggregateEventShards

final class AggregateEventShards[Event <: AggregateEvent[Event]] extends AggregateEventTagger[Event]

The base type of PersistentEntity events may return one of these to make the events available for sharded read-side processing.

The tag should be unique among the event types of the service.

The numShards should be stable and never change.

The class name can be used as tag, but note that it is needed to retain the original tag when the class name is changed because the tag is part of the store event data.
