Here is the config I am using...
I am using the dynamodb akka persistence plugin right now and it works fine
when it is in there.
If I take out the persistence configuration all together then cluster
sharding does not start up, I see this error:
16-04-07 01:06:14,514 [test] ERROR |
[project-akka.actor.default-dispatcher-2] (a.a.OneForOneStrategy:71) |
AKKA_SOURCE=akka://project/system/sharding/MyEntity/-28 | requirement
failed: default journal plugin is not configured, see 'reference.conf'
akka.actor.ActorInitializationException: exception during creation.
Note: I am spinning up a docker cluster with this config, that is why the
remote section looks the way it does...
akka {
loglevel = "INFO"
loggers = ["akka.event.slf4j.Slf4jLogger"]
logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
extensions = [
"akka.cluster.client.ClusterClientReceptionist",
"akka.cluster.metrics.ClusterMetricsExtension",
"akka.cluster.ddata.DistributedData"
]
cluster.sharding.state-store-mode = ddata
# disables classic / legacy metrics
cluster.metrics.enabled=off
actor {
provider = "akka.cluster.ClusterActorRefProvider"
}
persistence {
journal.plugin = "dynamodb-journal"
}
remote {

netty.tcp {
bind-hostname = ${project.app.host}

}

}

heartbeating issues)

}
}
}
