JournaledGrain: Can other grain types receive the events raised inside a Grain?

[nkosi23]

Hello !

Can the events raised inside a JournalGrain be published and received by other Grain Types? If so how can this be done?

One of the nice things with event sourcing is the ability to have multiple subscribers for events.

This article helped clarified a confusion i've had about event sourcing, domain events and integration events:

And this stackoverflow question suggests that in Orleans publishing events must be done using streams (when publishing them is indeed the right thing to do):

Then the remaining question I have is: what would be the best way to design an aggregate JournaledGrain building its state using the events from multiple other grains (we can assume that we have access to the event store inside the grain).
