What it is

Apache Beam is a unified, language-agnostic framework for defining batch and streaming data-parallel processing pipelines that can execute on multiple distributed backends (Flink, Spark, Google Cloud Dataflow, Hazelcast Jet). It provides SDKs in Java, Python, Go, and TypeScript, allowing developers to write a pipeline once and run it on their choice of execution engine without rewriting code. Multi-language monorepo: sdks/ directory contains language-specific implementations (Java under sdks/java, Python under sdks/python, Go under sdks/go, TypeScript under sdks/typescript). Build orchestration via Gradle (build.gradle.kts) with custom Groovy plugins in buildSrc/ for Docker, module…

Open these first:

• build.gradle.kts — Root build configuration defining the unified Gradle build system, dependency management, and module coordination for the…
• README.md — Project overview describing Beam's unified model for batch and streaming pipelines and supported SDKs and runners.
• CONTRIBUTING.md — Contributor guidelines covering development workflow, testing, and code submission processes.
• buildSrc/src/main/groovy/org/apache/beam/gradle/BeamModulePlugin.groovy — Core Gradle plugin orchestrating module compilation, testing, and artifact generation for Beam modules.
• contributor-docs/release-guide.md — Release and versioning procedures essential for understanding project lifecycle and deployment cadence.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository with git clone https://github.com/apache/beam.git && cd beam. The project uses Gradle (Kotlin DSL, build.gradle.kts), so verify the Java version requirement in build.gradle.kts, then run `./gradle…

Daily commands:

No single 'dev server' — Beam is a library and pipeline framework. To run examples: (1) For Java: ./gradlew :runners:direct-java:run or similar runner-specific tasks. (2) For Python: activate virtualenv, run `python -…

…shortened for this brief.

Key cautions & unknowns

• Scorecard: dangerous CI workflow (0/10)
• 1. Multi-language builds: changing Java core may require regenerating Python stubs via gRPC; the build system handles this, but incremental rebuilds can be misleading—use clean builds when crossing language boundaries.…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
