DBOS for Go Durable Execution FAQs

Question 1

What is DBOS for Go?

Accepted Answer

DBOS is a framework for Go that provides durable execution, ensuring programs are resilient to failures by automatically resuming workflows from their last completed step using a PostgreSQL backend.

Question 2

How do I handle non-deterministic operations like API calls?

Accepted Answer

Non-deterministic operations must be wrapped in dbos.RunAsStep(). This allows DBOS to record the result and skip execution during recovery if the step has already successfully completed.

Question 3

Can I use DBOS with existing Go web frameworks?

Accepted Answer

Yes, DBOS is designed to integrate seamlessly with frameworks like Gin or the standard net/http library, allowing you to trigger durable workflows directly from your HTTP handlers.

Question 4

What makes a workflow deterministic in DBOS?

Accepted Answer

A deterministic workflow always produces the same sequence of steps given the same input. This means it cannot use direct randomness, direct time calls, or direct I/O; these must be wrapped in 'steps'.

Question 5

Why does DBOS require PostgreSQL?

Accepted Answer

DBOS uses PostgreSQL as a system database to store the persistent state of workflows and steps, allowing it to recover and resume execution accurately after a system crash or restart.
