I am confused, are you suggesting that spark is talking to the
journal data store directly, without any involvement of Akka / Akka
Persistence? If so, it sounds like a great solution but why would
that require an extension to the Akka Persistence design/API?
Well, another comment is that spark uses Akka actors in its
implementation, so I don’t see why it would magically be “much more
efficient”. I think we are mixing up two concerns here, will reply
later when I can type properly again.
This is a misunderstanding. As mentioned in my previous message, scaling
reads through a single journal actor doesn't work, it's not about that I
see a general performance issue with Akka actors.

Roland
