job-idempotency

What problem does it solve?

Idempotent background jobs prevent duplicate work and inconsistent state when retries occur, broker redeliveries happen, or scheduled tasks overlap. The skill provides patterns for wrapping handlers, transactional dedup, and lease-based locking to ensure safe retries and end-to-end correctness.

Core Features & Use Cases

• Idempotent wrapper around job handlers that checks a processed store and marks after successful execution.
• Transactional dedup: write the processed marker in the same transaction as the business logic to avoid partial commits.
• Scheduled-job safety: lease-based locking to prevent overlapping executions across workers.

Quick Start

Wrap your job handler with an idempotency guard that checks a processed store before executing and marks as processed after success.
