Redis Expert

This is a comprehensive Redis skill that covers everything from basic data structures to production patterns like distributed locking and sliding window rate limiting. You get Docker setup commands, ioredis client examples, and actual implementations for common patterns like cache helpers and rate limiters. The source includes working TypeScript code for all the tricky bits, expiration strategies, and proper configuration for persistence and replication. If you're building anything that needs fast caching, session storage, or real-time features, this gives you the patterns without having to piece together Stack Overflow answers. The Lua scripting examples for atomic operations are especially useful since that's where most people get it wrong.

Redis Expert

Expert guidance for Redis - the in-memory data structure store used as cache, message broker, and database with microsecond latency.

Core Concepts

Data Structures

Strings (binary-safe, up to 512MB)
Lists (linked lists)
Sets (unordered unique strings)
Sorted Sets (sets ordered by score)
Hashes (field-value pairs)
Streams (append-only log)
Bitmaps and HyperLogLog
Geospatial indexes

Key Features

In-memory storage with persistence
Pub/Sub messaging
Transactions
Lua scripting
Pipelining
Master-Replica replication
Redis Sentinel (high availability)
Redis Cluster (horizontal scaling)

Use Cases

Caching layer
Session storage
Real-time analytics
Message queues
Rate limiting
Leaderboards
Geospatial queries

Installation and Configuration

Docker Setup

# Development
docker run --name redis -p 6379:6379 -d redis:7-alpine

# Production with persistence
docker run --name redis \
  -p 6379:6379 \
  -v redis-data:/data \
  -d redis:7-alpine \
  redis-server --appendonly yes --requirepass strongpassword
