Each WordCount example introduces different concepts in the Beam programming model. Begin by understanding Minimal WordCount, the simplest of the examples. Once you feel comfortable with the basic principles in building a pipeline, continue on to learn more concepts in the other examples. Minimal Word...

Runner 是将用户通过调用Beam SDK构成的program(pipeline)进行编译转换,当我们指定任意一个Runner时,program就会被转化为与该Runner相兼容的可直接运行的程序,所以,在运行Beam程序时,需要指明底层的正确Runner类型 Beam 架构: 用户通过Beam Model构建一个数据处理管道(pipeline),调用Beam SDK API实现管道里的逻辑,也就是...
The key concepts in the Beam programming model are: PCollection: represents a collection of data, which could be bounded or unbounded in size. PTransform: represents a computation that transforms input PCollections into output PCollections.
To learn more about the Beam Model (though still under the original name of Dataflow), see the World Beyond Batch:Streaming 101andStreaming 102posts on O’Reilly’s Radar site, and theVLDB 2015 paper. The key concepts in the Beam programming model are: ...

Apache Beam is a unified model for defining both batch and streaming data-parallel processing pipelines, as well as a set of language-specific SDKs for constructing pipelines and Runners for executing them on distributed processing backends, including Apache Apex, Apache Flink, Apache Spark, and Go...

Apache Beam是一个开源的数据处理编程库,由Google共享给Apache的项目,前不久刚刚成为Apache TLP项目。它提供了一个高级的、统一的编程模型,允许我们通过构建Pipeline的方式实现批量、流数据处理,并且构建好的Pipeline能够运行在底层不同的执行引擎上。刚刚接触该开源项目时,我的第一感觉就是:在编程API的设计上,数据集...
