Hi, Following is my app.conf. I am losing almost 50% of the messages. Is it because of the ClusterRouterPool ?
Running it on 2 node cluster(each is m4.xlarge machine) There are two actors- akka { loglevel = "INFO" loggers = ["akka.event.slf4j.Slf4jLogger"] log-dead-letters-during-shutdown = off log-dead-letters = 0 stdout-loglevel = "INFO" log-config-on-start = off daemonic = off jvm-exit-on-fatal-error = on actor { provider = "akka.cluster.ClusterActorRefProvider" unstarted-push-timeout = 100s default-mailbox { mailbox-type = "akka.dispatch.SingleConsumerOnlyUnboundedMailbox" mailbox-push-timeout-time = 20s } default-dispatcher { type = Dispatcher executor = "fork-join-executor" fork-join-executor { parallelism-min = 16 parallelism-factor = 16 parallelism-max = 64 } throughput = 1 } producer-dispatcher { type = Dispatcher executor = "fork-join-executor" fork-join-executor { parallelism-min = 16 parallelism-factor = 4.0 parallelism-max = 64 } throughput = 1 } consumer-dispatcher { type = Dispatcher executor = "fork-join-executor" fork-join-executor { parallelism-min = 4 parallelism-factor = 4.0 parallelism-max = 4 } throughput = 1 } } remote { log-remote-lifecycle-events = on netty.tcp { hostname = "0.0.0.0" port = 2551 } } extensions = [ "akka.contrib.pattern.DistributedPubSubExtension" ] cluster { seed-nodes = [ "akka.tcp://myapp@0.0.0.0:2551", "akka.tcp://myapp@0.0.0.0:2552" ] auto-down-unreachable-after = 30s } } akka.contrib.cluster.pub-sub { name = myappPubSubMediator role = "" routing-logic = round-robin gossip-interval = 1s removed-time-to-live = 120s } spray.httpx { compact-json-printing = true } spray.can { server { pipelining-limit = 20 reaping-cycle = infinite request-chunk-aggregation-limit = 0 stats-support = off remote-address-header = on } client { max-connections = 64 max-retries = 5 parsing = ${spray.can.parsing} } parsing { max-uri-length = 4k max-response-reason-length = 64 max-header-name-length = 64 max-header-value-length = 8k max-header-count = 64 max-content-length = 512m max-chunk-ext-length = 512 max-chunk-size = 4m illegal-header-warnings = off } } This is how I am creating cluster Pool for both the actors - system.actorOf( ClusterRouterPool(AdaptiveLoadBalancingPool( SystemLoadAverageMetricsSelector), ClusterRouterPoolSettings( totalInstances = instances * 64, maxInstancesPerNode = instances, allowLocalRoutees = isLocal, useRole = None) ).props(Props[T]).withDispatcher(dispatcher), name) } Instances above is 16. Following are the versions - "io.spray" %% "spray-can" % "1.3.2", "io.spray" %% "spray-routing" % "1.3.2", "io.spray" %% "spray-testkit" % "1.3.2" % "test", "io.spray" %% "spray-client" % "1.3.2", "io.spray" %% "spray-json" % "1.2.6", "com.typesafe.akka" %% "akka-actor" % "2.3.6", "com.typesafe.akka" %% "akka-cluster" % "2.3.6", "com.typesafe.akka" %% "akka-contrib" % "2.3.6", "com.typesafe.akka" %% "akka-slf4j" % "2.3.6", "com.typesafe.akka" %% "akka-testkit" % "2.3.6" % "test" - Two actors: Producers and Consumers -- Sending in a following way - system.actorOf(ClusterClient.props(actorSet,Duration.create(10, TimeUnit.SECONDS))) clusterClient ! ClusterClient.Send(String.format("/user/%s", target), message, localAffinity = localAffinity) -- Throughput is 500 per second. -- Messages are being lost randomly. Tough to find any pattern. -- Can't find anything in the logs -- I even tried Bounded mailbox along with " automatic-back-pressure-handling = on" to make it blocking. But still losing messages. -- >>>>>>>>>> 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.
