About dbos-transact-py
DBOS Transact is an open source Python library for durable workflows backed by Postgres. It lives in the Python infrastructure and operations ecosystem, under orchestration and scheduling, and is distributed as the dbos package on PyPI under the MIT license. The project lets developers annotate ordinary functions as workflows and steps, then checkpoint state in Postgres so interrupted programs resume from completed work instead of starting over.
