Hi Guys, I am wondering if there is any recommended pattern to track the progress of the work done by the actor. For instance, we have 1000 files to read, parse, process and write. If I have readerActor, parserActor, processorActor, writeActor what would be the best way to track if all the files are completed. Currently I have custom counter inside each actor. But it gets complicated with actorpools and also when new children actors are created under these actors.
