Temporal Python Orchestration FAQs

Question 1

How do I test long-running workflows quickly?

Accepted Answer

The skill provides guidance on using the WorkflowEnvironment for time-skipping, which allows you to execute 'sleep' commands and timeouts instantly, testing months of workflow logic in seconds.

Question 2

What are the common pitfalls in Temporal Python development?

Accepted Answer

Common issues include violating determinism within workflow functions, failing to handle activity heartbeats in long-running tasks, and exceeding the 2MB payload limit for arguments or return values.

Question 3

How does this skill assist with the Saga pattern?

Accepted Answer

It provides implementation patterns for coordinating multiple microservice calls where failures trigger automated compensation activities to maintain data consistency across distributed systems.

Question 4

When should I use sync vs. async activities?

Accepted Answer

Use async activities for non-blocking I/O like API calls. Use sync activities with a ThreadPoolExecutor for blocking I/O (like legacy DB clients) or a ProcessPoolExecutor for CPU-intensive tasks to avoid blocking the event loop.

Question 5

What makes a workflow deterministic in Temporal?

Accepted Answer

Determinism requires that workflow code yields the same results every time it is replayed. You must avoid non-deterministic functions like datetime.now() or random() and never perform direct I/O; instead, use Temporal-safe wrappers or move side effects into Activities.
