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.
