I believe Martin may have kindly answered, at least part of, this
question in another thread.
If I may paraphrase him: the way Akka Persistence Views work currently
(polling) is an implementation detail and later versions of Akka
Persistence may provide a push-based approach as well.
If journal replication is still used as the means of distribution then
perhaps Views will just subscribe to a Processor (effectively the
Processors's journal) and get pushed events in messages (without the
Processor even running locally).
Not exactly totally reactive - I assume it depends upon how the
journals are replicated - but it could work.
Of course, it's very likely that I am completely confused ;-)
The availability of (new) events in the journal is also an event.
Whether a view is actively notified about their availability (= push) or
if the view tries to find out itself (= pull) is rather a technical
detail. A pull-based view even allows to decouple a processor from its
view(s) in the dimension of lifetime. Why do you see this in conflict
with being reactive?
