SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Redis-based distributed locks coordinate access to shared resources across multiple services, preventing race conditions and ensuring safe, serialized execution.

Core Features & Use Cases

Atomic lock acquire/release: Lua scripts ensure only the owner can release, and operations are atomic.
TTL-based safety: Locks auto-expire to avoid deadlocks; supports renewal.
Use cases: Protects critical sections in distributed queues, scheduled jobs, and co-ordination across microservices.

Quick Start

Instantiate a RedisLock with a Redis client and a lock key, set expiry, then attempt to acquire the lock with TryAcquireCtx and finally release with ReleaseCtx after the protected operation.

FAQPage Schema

How do I implement a distributed lock with Redis to prevent race conditions?▼

You implement a Redis distributed lock using Lua scripts for atomic acquire, release, and renewal operations. This coordinates access to shared resources across microservices, preventing race conditions during concurrent operations and scheduled jobs.

Why should I use Lua scripts for Redis distributed locks?▼

Lua scripts ensure atomic lock acquire and release operations in Redis, guaranteeing that only the lock owner can release it. This atomicity prevents race conditions and avoids lock hijacking by unauthorized services.

How do I avoid deadlocks when acquiring a distributed lock in Redis?▼

Avoid deadlocks by setting TTL-based expiry on Redis distributed locks. Locks auto-expire if the holding service crashes or stalls, and the lock supports renewal to extend the TTL during long-running protected operations.

How do I safely release a Redis distributed lock without lock hijacking?▼

Safely release a Redis distributed lock by using unique lock identifiers checked within a Lua script. The script verifies the identifier before deletion, ensuring only the original owner can release the lock and preventing hijacking.

Can I use Redis distributed locks for scheduled jobs across microservices?▼

Yes, Redis distributed locks coordinate access to shared resources and protect critical sections in distributed queues and scheduled jobs. They ensure safe, serialized execution of concurrent operations across multiple microservices.
