@ArturKarbone good to know
@Arkatufus I'd never forgo a database completely
it's role in a stateful application is different than it's role in a stateless one though
a database is just backup storage for state - it's designed to store state that isn't being used and keep a cold copy of the state that's being actively used in the event of a crash or failure
fyi, we're talking about an application / production database here - should be treated separately from a reporting database or any sort of back office thing
SQL Server has, unfortunately, trained a lot of developers into using a single database for both purposes
but that's a subject for a different day
your application state should always be the source of truth
for when your application is live and running
the database should be there to re-hydrate that application state when it needs to be used
so your relationship with your database becomes much more write-heavy than read-heavy

@Aaronontheweb how does reporting database fit in this akka.net application?

well reporting would usually come off something like OLAP, to get to that there are several options. Eg EventSourced. More traditional would be using object db for your event/command store, think transactional and use that to generate rdb that you then denormalise into the OLAP.
