The origami project provides "Monadic folds" to process streams of data in a composable fashion.
With monadic folds you can:
-
accumulate state, for example count the number of elements or compute a hash value
-
output results to a file or a database as you compute them
-
display the end value on the console
Moreover folds are composable:
-
you can implement and test folds independently from the data stream they will be used on
-
you can run two folds at the same time without having to make two passes over the data stream
-
you can add side-effects like writing results to a file later on if you need to
Finally, side-effecting folds like Sinks are operating inside a SafeT monad to make sure that resources are always released, even when there are exceptions.
