distributed-locking

What problem does it solve?

Distributed coordination and locking across services to prevent concurrent execution of critical sections and ensure single-active workers.

Core Features & Use Cases

• Redis-based distributed locking (SET NX) with TTL
• Fencing tokens to prevent stale lock actions
• PostgreSQL advisory locks for DB-bound operations
• Redlock for multi-node Redis deployments
• Common failure modes and mitigations

Quick Start

Use a Redis-based lock with a TTL around your critical section to ensure only one process runs at a time.
