Use when working with Beam YAML code in sdks/python/apache_beam/yaml/. +--- + +# YAML Development in Apache Beam + +## Project Structure + +### Key Files in `sdks/python/apache_beam/yaml/` +- `integration_tests.py` - Runs integration tests defined in YAML files or using testcontainers. +- `main.py` - Entry point for running YAML pipelines from the command line. +- `pipeline.schema.yaml` - JSON schema defining the valid structure for Beam YAML pipelines. +- `standard_io.yaml` - Declarations of standard IO transforms and their mappings to providers. +- `standard_providers.yaml` - Configuration for standard providers (e.g., Java expansion services). +- `yaml_combine.py` - Implementations for aggregation and combining operations. +- `yaml_io.py` - Python implementations for builtin IOs (PubSub, BigQuery, Iceberg, etc.). +- `yaml_join.py` - Implementations for join operations. +- `yaml_mapping.py` - Implementations for mapping operations (e.g., `MapToFields`). +- `yaml_provider.py` - Manages providers (Python, Java cross-language) that implement transforms. +- `yaml_transform.py` - Core YAML expansion logic, parsing, and translation to Beam pipelines. + +## Environment Setup +Since Beam YAML is implemented within the Python SDK, the environment setup is identical to Python development. Refer to the `python-development` skill for details on using `pyenv` and installing in editable mode (`pip install -e .[gcp,test]`).
