I was part of a team that processed really large files (hundereds of GB) in an Akka cluster. At that time Akka seemed like a clever choice to us, since we were Scala enthusiats and Akka was the framework of the day, but it took us many weeks to master (more or less) Akka. We could have done the same in a more robust and manageable way with Spring Batch in a fraction of the time. Akka had a really steep learning curve for doing relatively boring things. Technically it was quite interesting, a from a business perspective it was a desaster.
