DBOS, a durable workflow engine built on Postgres, uses Postgres' features to store workflow state, providing "save points" that enable recovery from crashes. DBOS functions, written in Python or TypeScript, use decorators to manage workflow steps, storing each step's state and output in the Postgres database for deterministic execution.

HOW TO THINK ABOUT TIME

Physical time (instants and durations measured in seconds) is different from civil time (datetimes and periods based on calendar systems like the Gregorian calendar), as there are more complexities and potential for bugs when dealing with civil time. It's important to use well-defined time zones (like those from the IANA database) and avoid ambiguous types like "zoned datetime.” This guide provides language-specific API recommendations for handling date and time operations well.
