Why Is Redis So Fast? Inside Its Memory Storage, Data Structures, I/O Multiplexing, and Network Protocols

Redis achieves millisecond‑level latency by storing all data in memory, using specially optimized data structures such as SDS, incremental‑rehash hash tables, and ziplists, employing a single‑threaded event‑driven model with epoll‑based I/O multiplexing, and streamlining network communication through the compact RESP protocol, compression, and batching, while also offering flexible eviction and persistence strategies.
