I just wrote a program to read PowerMTA accounting files and record email bounces. Clojure's lazy data structures make it possible to process large amounts of data in very reasonable amounts of memory - and pretty fast too. In less than 140 lines of very well-commented Clojure, I have a complete email event processing library and it can process 450,000 lines of CSV file, extract 46,000 bouncing emails and record their status in MySQL, in about 80 seconds. I continue to be more and more impressed by Clojure...
I spent the morning putting in a comma and the afternoon removing it.
