Non-Retryable Error
Definition

An error for which an unchanged repetition is unlikely to succeed and therefore requires different handling.
Simply explained
If an input is incorrect, resending the same input is unlikely to help.
Why it matters in practice
Helps develop and operate digital systems robustly, securely, and maintainably.
Example from business
An invalid schema input is immediately reported for correction instead of being sent multiple times.
Limits and pitfalls
- Treat all 4xx responses categorically as non-repeatable or ignore context changes.
Origin & history

Use in mid-sized companies
