Redis Deep Dive — Architecture, Internals Handbook

Trust me, this is all you need for Redis. Thats it!!.

A complete, deeply-researched Redis handbook built for tech interview prep — and for anyone who wants to actually understand what Redis does behind its deceptively simple commands.

What's inside (117 pages):

• Architecture & internals — the event loop, RESP protocol, threading model, and exactly how a command travels from socket to reply
• Every core data structure (Strings, Lists, Hashes, Sets, Sorted Sets, Streams, Bitmaps, HyperLogLog) with time complexity for each operation
• Persistence, replication, Sentinel failover, and Redis Cluster — fully explained with diagrams
• Memory management, eviction policies, transactions, Lua scripting, Pub/Sub, and security/ACLs
• Real-world system design patterns: caching, rate limiting, distributed locking, leaderboards, message queues
• 105 interview questions with full answers — graded from fundamentals to staff-level internals, plus system-design and coding questions
• A one-page cheat sheet and full reference list
