The Art of Incremental Stream Processing

Purely functional, elegant, correct, incremental and composable stream processing that is CPU and memory efficient. This is our (worthy) goal, but where do we start?

This problem space is being extensively explored across a variety of languages and libraries, each with subtly different trade-offs and not-so subtly different APIs and terminology. However, these libraries share common goals, and most share common ancestry from Oleg Kiselyov’s original Iteratee work or its Free Monad based derivatives.

This talk aims to build up an intuition for stream processing in general by first building up the core concepts and language of stream processing, and then grounding those by carefully examining the trade-offs and internals of several productionised implementations. Of particular interest are the pipes and conduits libraries from the Haskell community, and scalaz-stream from the Scala community.
