Akka's Materializer

Akka Toolkit has a Materializer SPI (Service Provider Interface) to support the Materialization component for Akka Stream-based Graphs:

package akka.stream 
abstract class Materializer { 
  // SPI 
} 

If we want our own customized Materializer, we should provide the implementation to this abstract class. However, the Akka Streams API has provided a default implementation for running Akka Stream's Graph—ActorMaterializer:

• If required, we can create our own Materializer
• We can use any Materializer implementation to execute our Data Flow Graphs (Graphs or RunnableGraphs)
• The Akka Streams API uses ActorMaterializer as the default Materializer
