Show HN: Mr. Graph – A graph definition and execution library for Python
by jmcminis on Hacker News.
What: Mr. Graph is a python library designed to make composing graphs of sync and async functions easy! Use google style docstrings to automagically create dataclasses and chain together function calls into graphs. Why: I like the design of Dagster, but not the latency. For apps and systems engineering, sometimes I want to compose a graph out of regular python functions. I don;t need all the heavy machinery that comes with a full workflow engine. Current features: – Use with either async or sync functions – Uses google style doc strings to name return values. – Creates dataclasses for each function’s output. – Can infer pipelines from input and output signatures – All directed acyclic graph layouts supported. linear, fan-in, fan- out. Future Features: – Better examples for use with async calls (like LLMs) – Splitting dataclasses, better error handling, logging improvements. This is under active development. Any feedback, interest, or contributions are appreciated. Thanks! github link: https://ift.tt/hJ9Ii3z
