About linyiqun/Redis-Code

Redis-Code is an open-source project hosted on GitHub that provides a systematic source code analysis of the Redis key-value database. The repository is organized into logical modules including data structures (adlist, dict, sds, ziplist, zipmap), data operations (AOF, RDB, replication, transactions), event handling (epoll, kqueue, select), networking (anet, networking), and tools (bitops, compression, SHA1, CRC64). It also highlights 11 great designs in Redis such as HyperLogLog, zmalloc, multi transactions, redis-benchmark, zipmap, sparkline, object reference counting, fork-based background processes, long-to-string conversion, regex implementation, and drand48() reimplementation. The project is primarily documented in Chinese and targets developers who want to understand Redis internals.
