Apache Beam is an open‑source unified programming model for building both batch and streaming data‑parallel pipelines, exposing a portable API that can be run on diverse back‑ends such as Apache Flink, Spark, Dataflow, and others. It provides SDKs (Java, Python, Go, etc.) so **end users** can write pipelines without worrying about execution details, **SDK authors** can create language‑specific abstractions insulated from runner specifics, and **runner developers** can plug in new execution environments while remaining shielded from SDK internals.
