# 0002 — Job timeouts with exponential backoff, max 3 attempts
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
Simple retries caused cascade failures. Transient failures need backoff.
|
||
|
|
|
||
|
|
## Decision
|
||
|
|
|
||
|
|
Jobs timeout after 5 minutes. Failed jobs retry with exponential backoff (1s, 2s, 4s) up to 3 total attempts. Permanent failure escalates to review queue.
|
||
|
|
|
||
|
|
## Consequences
|
||
|
|
|
||
|
|
Better resilience. Reduced cascading failures. Terminal failures tracked for review.
|
||
|
|
|
||
|
|
## Alternatives rejected
|
||
|
|
|
||
|
|
Circuit breaker rejected (adds complexity without benefit at this scale).
