Akka (7) -Configuration

There are serval places which we can configure Akka:

  • log level and logger backend
  • enable remote
  • message serializers
  • definition of routers
  • tuning of dispatchers

Two important concepts we need to understand when we do configuration:

  • Throughput
    It defines the number of messages that are processed in a batch before the thread is returned to the pool.
  • parallelism factor
    The parallelism factor is used to determine thread pool size using the following formula: ceil (available processors * factor). Resulting size is then bounded by the parallelism-min and parallelism-max values.
