Dataflow Tutorial: Stream and Batch Processing on GCP
Dataflow runs Apache Beam pipelines as a managed service, with one programming model for batch and streaming. This tutorial explains the model, runs a real pipeline locally on 77,033 taxi trips with a batch branch and a windowed branch, and covers windows, watermarks, late data, templates and how to run on Dataflow.
