⚙️ What is Determinism?
Determinism means that a system or function, given the same input and starting state, will always produce the same output and follow the same execution path—no randomness, no surprises.
🔁 Why Determinism Matters in Distributed Systems
In distributed systems—especially in workflow engines like Temporal—determinism is essential for:
- Replayability: To recover workflow state after failure by replaying past events
- Consistency: Ensuring the same steps are followed every time
- Debuggability: Easier to trace, test, and reproduce bugs
- Fault tolerance: The system can safely retry or resume after crashes
