Welcome to Stagegate

stagegate is a small, explicit, single-process Python library for running many forward-only pipelines under stage-aware priority and abstract resource quotas.

It is intended for local batch workloads that need more structure than a plain thread pool, but less machinery than a workflow engine.

• User’s Guide explains the design background, mental model, and scheduling approach.

• Use Cases shows the intended API patterns for barriers, incremental collection, cancellation, cooperative terminate, and long-lived outer loops.

• API Reference provides generated reference documentation for the public API.
