akka - Parallel file processing in Scala

Question

Suppose I need to process files in a given folder in parallel. In Java I would create a FolderReader thread to read file names from the folder and a pool of FileProcessor threads. FolderReader reads file names and submits the file processing function (Runnable) to the pool executor.

In Scala I see two options:

• create a pool of FileProcessor actors and schedule a file processing function with Actors.Scheduler.
• create an actor for each file name while reading the file names.

Does it make sense? What is the best option?

Answer 1

Depending on what you're doing, it may be as simple as

for(file<-files.par){
   //process the file
}
