Apache Beam is an open-source, unified model that allows users to build a program by using one of the open-source Beam SDKs (Python is one of them) to define data processing pipelines. Unlike MapElements transform where it produces exactly one output for each input element of a collection, ParDo gives us a lot of flexibility so that we can return zero or more output for each input element in a collection. The following are 7 code examples for showing how to use apache_beam.Keys().These examples are extracted from open source projects. Filters input string elements based on a regex. ParDo core operation load tests for streaming with 4 tests cases that loads data from SyntheticSources and runs on Dataflow. Introduction. November 02, 2020.
