Apache Beam is one of the latest projects from Apache, a consolidated programming model for expressing efficient data processing pipelines as highlighted on Beam's main website [].Throughout this article, we will provide a deeper look into this specific data processing model and explore its data pipeline structures and how to process them. It can be either a fixed number, or it can generate rows indefinitely. The pipeline is then executed by one of Beam's supported distributed processing back-ends, which include Apache Flink, Apache Spark, and Google Cloud Dataflow. You define a pipeline with an Apache Beam program and then choose a runner, such as Dataflow, to run your pipeline. Go offers no generics, except for a few built-in datatypes. org.apache.beam.sdk.values PCollection.
