TiDB is a distributed SQL database. Inspired by the design of Google F1, TiDB supports the best features of both traditional RDBMS and NoSQL.

Horizontal scalability

Grow TiDB as your business grows. You can increase the capacity simply by adding more machines.

Asynchronous schema changes

Evolve TiDB schemas as your requirement evolves. You can add new columns and indices without stopping or affecting the on-going operations.

Consistent distributed transactions

Think TiDB as a single-machine RDBMS. You can start a transaction that acrosses multiple machines without worrying about consistency. TiDB makes your application code simple and robust.

Compatible with MySQL protocol

Use TiDB as MySQL. You can replace MySQL with TiDB to power your application without changing a single line of code in most cases.

Written in Go

Enjoy TiDB as much as we love Go. We believe Go code is both easy and enjoyable to work with. Go makes us improve TiDB fast and makes it easy to dive into the codebase.

Multiple storage engine support

Power TiDB with your most favorite engines. TiDB supports most of the popular storage engines in single-machine mode. You can choose from goleveldb, LevelDB, RocksDB, LMDB, BoltDB and even more to come.
