Скачать или смотреть Temporal Unscripted: Compensating Transactions (part of Saga Pattern) in Python

When something goes wrong between your microservices, how do you make it look like it never happened? The Saga Design Pattern is everywhere, and one important piece of it is writing compensating actions, a design pattern in itself! Emily Fortuna and Andrew Fitz Gibbon (Fitz) discuss and live code through implementing compensating actions in a Temporal Workflow using Python.

Protip! If "Live Coding" in real time is too slow for you, don't forget you can adjust the playback speed by using the little gear on the right hand corner of the video!
