Hi Ramon,
in eventsourced, the application was responsible for delaying new
messages to a processor until recovery completes (otherwise new messages
could wrongy interleave with replayed messages). This is not necessary
anymore with akka-persistence. New messages are internally buffered
until recovery completes (see also migration guide
<http://doc.akka.io/docs/akka/2.3.0/project/migration-guide-eventsourced-2.3.x.html>).
Akka-persistence doesn't notify applications with a separate message
when recovery completed but you can easily achieve that by sending a
processor a non-Persistent message immediately after creation. The
processor will then receive this as first message immediately after
recovery completed which is equivalent to a recovery-completed
notification. You could even send that message from an overridden
preStart or preRestart.
Cheers,
Martin

Hi All,
I am currently converting my framework over to akka-persistence from
eventsourced.
I want to be notified when the recovery is complete, and do some work
before accepting new messages.
How would I know that recovery is complete ?
Would I need to overide preRestart and somehow poll self for the
existence of recoveryFinished ?
Specifically what I need to do is reset counter so that new keys,
begin where they last left off.
I have another method which I may use but was hoping for a hook I
could reuse.
thanks
