Hi, Cluster Sharding uses persistence to ensure that if the shard coordinator crashes, the current sharding state can be replayed on a new shard coordinator node (Described in this section of the docs: http://doc.akka.io/docs/akka/2.4/scala/cluster-sharding.html#How_it_works)
You can configure sharding to use a separate journal by setting akka.cluster .sharding.journal-plugin-id and akka.cluster.sharding.snapshot-plugin-id. That configuration entry with a json serializer for PeristentRepr looks strange, that is an internal plugin API, here's a section in the docs about providing a human readable format for the journal (I'm guessing that is what you are after): http://doc.akka.io/docs/akka/2.4/scala/persistence-schema-evolution.html#Store_events_as_human-readable_data_model -- Akka Team Lightbend <http://www.lightbend.com/> - Reactive apps on the JVM Twitter: @akkateam -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
