I have quite large files that I need to deal with (500Meg+ zip files).
Are there any non-blocking IO open source implementations for Scala\'s actors?
Not that I know of, but you could probably get a lot of mileage out of looking at Naggati, a Scala wrapper around Apache Mina. Mina is a networking library that uses NIO, Naggati translates this into a Scala style of coding.
