Hi Francesco, In general the GraphStage is meant to encapsulate smaller graph transformations than sub-graphs and the flow API and GraphDSL is the way to go combine graphs. So, one thing might be to reconsider if perhaps your GraphStage is doing too many things at one time and you could separate concerns into smaller parts which can then more freely be combined.
If you have already considered this but feel sure about your design, then the materializer is available inside your graph stage logic through the materializer method. It would be very interesting to hear about the use case! -- Johan Andrén Typesafe - Reactive apps on the JVM Twitter: @apnylle On Monday, December 7, 2015 at 4:37:52 PM UTC+1, Francesco Di Muccio wrote: > > Hi, > > in all the other stages it is possible to get the Materializer from the > LifecycleContext to materialize sub-graphs, but in GraphStage it isn't > possible, is it by design? > > What is the best way to materialize a sub-graph within a GraphStage?
