You can increase the capacity simply by adding more machines. 10 11 - __Asynchronous schema changes__ 12 Evolve TiDB schemas as your requirement evolves. You can add new columns and indices without stopping or affecting the on-going operations. 13 14 - __Consistent distributed transactions__ 15 Think TiDB as a single-machine RDBMS. You can start a transaction that crosses multiple machines without worrying about consistency. TiDB makes your application code simple and robust. 16 17 - __Compatible with MySQL protocol__ 18 Use TiDB as MySQL. You can replace MySQL with TiDB to power your application without changing a single line of code in most cases. 19 20 - __Written in Go__ 21 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. 22 23 24 - __NewSQL over TiKV__ 25 Turn [TiKV](https://github.com/pingcap/tikv) into NewSQL database 26 27 - __Multiple storage engine support__ 28 Power TiDB with your most favorite engines. TiDB supports many popular storage engines in single-machine mode. You can choose from GolevelDB, LevelDB, RocksDB, LMDB, BoltDB and even more to come. 29 30 31 ## Roadmap 32 33 Read the [Roadmap](./docs/ROADMAP.md). 34 35 ## Quick start 36 37 Read the [Quick Start](./docs/QUICKSTART.md) 38 39 ## Architecture 40 41  42 43 ## Contributing 44 Contributions are welcomed and greatly appreciated.
