## TL;DR

Redis supports rich data types beyond simple key-value: String, List, Set, Sorted Set, Hash, Bitmap, HyperLogLog, Geospatial, Stream. Each type has specialized atomic operations — Redis is often called a 'data structure server'. Streams (Redis 5.0, 2018) enable message queue and event sourcing patterns.

## Core Explanation

Strings: `SET key val`, `INCR` (atomic counter). Lists: `LPUSH/RPUSH`, `LPOP/RPOP` — queue/stack. Sets: `SADD`, `SINTER` (intersection). Sorted Sets: `ZADD key score member`, `ZRANGE` — leaderboards. Hashes: `HSET user:1 name Alice` — object storage. Streams: `XADD mystream * field value`, consumer groups for reliable message processing.
