A Chinese developer has published a detailed blog series documenting the creation of AdvisKV, a distributed key-value storage system prototype written entirely in C++17. The project includes four main modules: Meta, SDM, Storage, and SDK, and implements core distributed systems features such as database and table creation, routing queries, KV read/write operations, dynamic replica scaling, bad replica replacement, Raft consensus, and WAL/snapshot recovery. The author has also run gtest unit tests to validate functionality. This hands-on project provides valuable insights for engineers interested in building distributed systems from the ground up, covering both theoretical concepts and practical implementation details. The series is particularly useful for those looking to understand the internals of distributed storage systems.
