## What it is
A Go library providing a simplified distributed locking implementation built on Redis. It supports obtaining, refreshing, releasing, and TTL-checking locks, plus fencing tokens for safe lock-loss mitigation.

## Use cases
- implement distributed locks across multiple service instances
- prevent concurrent cron jobs from running twice
- coordinate access to a shared resource using Redis
- add fencing tokens to distributed locking
- acquire and refresh locks with TTL in Go
- build a mutex backed by Redis

## When to choose
- you need a small, focused distributed lock library for Go with Redis
- you want fencing token support to guard against GC-pause lock loss
- you already use go-redis and want a simple Obtain/Refresh/Release API

## When to avoid
- you need multi-node consensus locking without trusting a single Redis instance (e.g. Redlock across clusters)
- your project is not in Go
- you need locks persisted outside Redis

## Facets
- artifact type: library
- maturity: active
- function: caching, concurrency, database-driver
- domain: databases, microservices, developer-tools
- platform: go, windows, self-hosted
- tags: redis, distributed-lock, golang, fencing-tokens, mutex, synchronization, linux, macos, docker
