[akka-user] Akka Persistence and store events for external consumption

2015-03-04 Thread Hannes Stockner
Hello, I am using Akka Cluster Sharding because I have many stateful actors that together don't fit on one machine. Additionally I am also using Akka Persistence (with Cassandra journal) for the snapshot mechanism (to recreate state). For storing the events I would like to use a user defined

Hi Tim! I can’t reproduce what you mention, which exact jar are we talking about? I downloaded the source jar from:  http://search.maven.org/#artifactdetails%7Ccom.typesafe.akka%7Cakka-stream-experimental_2.11%7C1.0-M4%7Cjar and it does seem to contain valid javadoc, or am I missing something? //

I wanted to open a quick discussion on this before reporting a bug; is there a reason (other than nobody has implemented it yet) why the Scaladocs are not included in the akka-stream-experimental release? Any sense of the complexity / what is needed to change that? I'd like to get the docs

Hi, That is by design. Calling onError inside the ActorPublisher will Terminate the stream with the failure (it's in the doc for the method). If you on the other hand throw an exception during your processing I assume that the SupervisionDecider will decide what to do. B/ On 3 March 2015 at
