Re: [akka-user] Why isn't akka PersistenceQuery using the Event Adapter configuration?

2016-08-07 Thread Patrik Nordwall 
This is by design. See discussion in
https://github.com/akka/akka/issues/18050. It should be done in the plugin
implementations where the necessary information is available. I have create
a feature request in the Cassandra plugin.

Re: [akka-user] Why isn't akka PersistenceQuery using the Event Adapter configuration?

2016-07-29 Thread Konrad Malawski 
I believe this was by design actually if I remember correctly, as we
considered the read side may want to operate on the raw events by default.

Let's say that in the same app that needs adapters for the PersistentActors
you want to project a view from historical data,
thus you may not want to apply the adapters for example.

It is possible to apply the adapters manually, as I explained here:
https://github.com/akka/akka/issues/21065

I agree however that it would be nice to make this simpler.
Ideas and contributions how the API could be improved are very welcome :-)

Hey there,

  Recently I tried out Akka Persistence, and I used a Event Adapter.
  All works really well on the Journal side, but then I started trying to
use the PersistenceQuery side, and I noticed that the events in the stream
come "un-event-adapted", that is, the method "fromJournal" is never called
on the adapter.
  And since the EventEnvelope doesn't contain the manifest from
PersistentRepr, one can't just map the "fromJournal" over the stream.

  Am I missing something? Maybe I misconfigured something? Or is this on
purpose?
