Duplicate Job Execution Prevention
The job handling system includes a critical fix to prevent the same job from being executed multiple times. This is achieved by:
1. Early Status Check: The system immediately checks if a job's status is already COMPLETED, FAILED, or CANCELLED before execution. If so, the worker exits immediately.
2. Atomic Status Updates: Job statuses are updated atomically in Redis to prevent race conditions where a job might be picked up by another worker before its status is updated.
This ensures that each job is processed exactly once, preventing redundant operations and inconsistent outputs.
