Redis: High Performance Cache

Redis is an in-memory data structure store, used as a database, cache, and message broker.

Quick Deployment

docker run --name my-redis -d redis

Persistence

Redis offers two modes: RDB (snapshots) and AOF (Append Only File). To enable persistence:

version: "3.8"
services:
  redis:
    image: redis:alpine
    command: redis-server --appendonly yes
    volumes:
      - ./redis_data:/data
    ports:
      - "6379:6379"

Common Use Cases

1. Session Cache: Storing user tokens.
2. Task Queues: Backend for Celery or BullMQ.
3. Leaderboard: Using Sorted Sets.
