Paper notes: Stream Processing at Google with Millwheel

MillWheel: Fault-Tolerant Stream Processing at Internet Scale


Akidau et. al., VLDB 2013

The big idea: Streaming computations at scale are nothing new. Millwheel is a standard DAG stream processor, but one that runs at ‘Google’ scale. This paper really answers the following questions: what guarantees should be made about delivery and fault-tolerance to support most common use cases cheaply? What optimisations become available if you choose these guarantees carefully?
