In the Akka framework, each AkkaSystem has a default MessageDispatcher. An Actor uses that default dispatcher, if no dispatcher is configured to it. If required, we can configure our application required MessageDispatcher.
In the Akka framework, the Dispatcher component internally uses Java's Executor framework to execute tasks asynchronously. The Akka framework has provided the following implementations of Java's Executor framework:
- default-executor: It is the default Executor implementation used by the Akka framework if we don't provide this configuration. It uses java.util.concurrent.ExecutorService to execute asynchronous tasks.
- fork-join-executor: It uses Java's Fork/Join Executor framework to execute asynchronous tasks.
- thread-pool-executor: It uses a predefined thread pool to execute asynchronous tasks.
