Storage API Reference

FlowyML uses a pluggable storage layer that separates artifact storage (binary outputs of each step) from metadata storage (run history, step status, and lineage graphs). Every backend implements a common interface, so you can swap providers — local disk during development, cloud object stores in production — without changing pipeline code.

Storage backends for flowyml:

• Artifact Stores: Storage for step outputs (GCS, Local, etc.)
• Metadata Stores: Storage for run metadata and lineage (SQLite, etc.)
