Hi Akka Team,
I have 100 threads, need to process only 12 threads at a time not more than
that. After completion of these threads other 12 have to be processed and
so on but it's processing only first 12 set threads then it terminates
after that.
Here is my Logic:
class AkkaProcessing extends Actor {
def receive = {
case message: List[Any] =>
var meterName = message(0) // It Contains only 12 threads as a set, it
process them and terminates. Am unable to get remaining threads
println("The Akka Meter is :" +meterName)
val sqlContext = message(1).asInstanceOf[SQLContext]
val FlagDF = message(2).asInstanceOf[DataFrame]
{
All the business logic here
}
context.system.shutdown()
}
}
}
object Processing {
def main(args: Array[String]) = {
val rawBuff = new ArrayBuffer[Any]()
val actorSystem = ActorSystem("ActorSystem") // Creating ActorSystem
val actor =
actorSystem.actorOf(Props[AkkaProcessing].withRouter(RoundRobinPool(200)),
"my-Actor")
implicit val executionContext =
actorSystem.dispatchers.lookup("akka.actor.my-dispatcher")
for (i <- 0 until meter_list.length) {
var meterName = meter_list(i) // All 100 Meters here
rawBuff.append(meterName, sqlContext, FlagDF)
actor ! rawBuff.toList
}
}
}
Apllication.conf
ActorSystem {
akka {
log-config-on-start = on
log-dead-letters-during-shutdown = off
actor {
timeouts {
verySmallAskDuration = 5000
}
# Frequency with which stopping actors are prodded in case they
had to be
# removed from their parents
reaper-interval = 7s
provider = "akka.actor.LocalActorRefProvider"
my-dispatcher {
type = Dispatcher
executor = "fork-join-executor"
fork-join-executor {
# Throughput defines the maximum number of messages
to be
# processed per actor before the thread jumps to the
next actor.
# Set to 1 for as fair as possible.
throughput = 1000
# Min number of threads to cap factor-based
parallelism number to
parallelism-min = 2
# Parallelism (threads) ... ceil(available processors
* factor)
parallelism-factor = 3
# Max number of threads to cap factor-based
parallelism number to
parallelism-max = 12
}
}
}
}
akka.actor.deployment {
/my-Actor {
dispatcher = my-dispatcher
}
}
}
Any help highly appreciated
Thanks
Abhishek
