TiDB Overview: Architecture, Storage Model, and Execution Plan
TiDB is an open‑source, MySQL‑compatible distributed database that unifies OLTP and OLAP by using a stateless SQL layer, a Placement Driver for metadata and Raft‑managed TiKV/TiFlash storage, key‑value mapping with RocksDB, and a push‑down execution engine that splits work between coprocessor and root tasks for scalable, highly available workloads.
