Episode notes
Temporal Simplifies Distributed Logic
- Traditional background tasks and queues spread business logic thin and force developers to manage complexity manually.
- Temporal abstracts distributed application complexity, letting developers focus on straightforward business logic.
Durable Execution Explained
- Durable execution preserves full code state durably, eliminating crashes and complex state management.
- It enables writing programs that can run for any duration, even with blocking calls like sleep for 30 days.
Use Activities for IO
- Do not perform direct IO in workflow orchestration functions; keep them deterministic.
- Place all external API calls in activities which Temporal automatically retries on failure.
