pyowa

pyowa is a Python library that provides a lightweight framework for orchestrating asynchronous workflows and data processing across services. It aims to help developers define task graphs, manage dependencies, and schedule executions in a consistent, observable way, with an emphasis on simplicity and portability for small to medium-scale projects.

Core concepts include a declarative task definition, an engine that resolves a directed acyclic graph of tasks, and workers that execute tasks. The architecture is modular, with pluggable backends for messaging queues and storage. It supports asyncio-based tasks, configurable retry strategies with backoff, and time-based scheduling. Observability features include built-in metrics, structured logging, and optional distributed tracing.

pyowa is designed to minimize external dependencies and to be easy to extend. It runs on CPython 3.8 or later and can be installed from PyPI. The project emphasizes testability and provides a small set of integration hooks for common data stores and message systems.

History and development: the project originated as a community-driven initiative in the Python ecosystem and has since reached a stable API with regular maintenance releases. It is released under an open-source license and maintained on a public repository.

Usage: after installation, users define tasks and a workflow graph, initialize an Engine, and start execution. Documentation covers task definitions, backends, error handling, and deployment considerations. See also other Python workflow tools such as Airflow, Luigi, and Prefect.
