What is TiDB?

TiDB (The pronunciation is: /'taɪdiːbi:/ tai-D-B, etymology: titanium) is a Hybrid Transactional/Analytical Processing (HTAP) database. Inspired by the design of Google F1 and Google Spanner, TiDB features infinite horizontal scalability, strong consistency, and high availability. The goal of TiDB is to serve as a one-stop solution for online transactions and analyses.

  • Horizontal scalability

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

  • 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.

  • Automatic Failover and high availability

Your data and applications are always-on. TiDB automatically handles malfunctions and protects your applications from machine failures or even downtime of an entire data-center.

  • Consistent distributed transactions

Think of 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.

  • Online DDL

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

  • Multiple storage engine support

Power TiDB with your most favorite engines. TiDB supports local storage engines such as GolevelDB and BoltDB, as well as TiKV, a distributed storage engine.
