cache-lock-guide

What problem does it solve?

Implementing robust concurrency controls to prevent double-submissions, race conditions, and unsafe state transitions by preferring cache locks over exclusive DB locks.

Core Features & Use Cases

• Guided pattern: Prefers cache locks (e.g., Cache::lock) to guard critical sections across distributed processes.
• Safeguards: Combines cache locking with transactional correctness to ensure atomic writes inside a guarded block.
• Use Case: Use in scenarios like preventing double submissions, race conditions in workflow transitions, or idempotent operations across distributed workers.

Quick Start

Acquire a distributed cache lock around the critical section to guard a shared resource.
