I got the idea of pulling the stream of events from the read model in order to update the projection.But how can i coordinate the activities of two instances of the app hosting the read model ? If both instances are woken up by a message published to the service bus, then they will pull the same stream of events from the event store, and they will try to apply it to the same projection (I mean to the same underlying storage where the projection is persisted). How can I coordinate these activities ? Is idempotency the way to go ? Am I missing anything ?
