Apache Beam

An open source, unified model for defining both batch and streaming data processing pipelines that run on any execution engine.

Apache Beam provides a portable SDK to build sophisticated data workflows using Java, Python, or Go. By decoupling the pipeline logic from the runtime, Beam allows developers to write code once and execute it on engines like Google Cloud Dataflow, Apache Flink, or Apache Spark. It excels at handling out-of-order data through robust windowing and triggers (essential for late-arriving events). Whether you are processing gigabytes of historical logs or millions of real-time sensor events per second, Beam ensures consistent results across diverse infrastructure.
