What is TiDB?

TiDB (The pronunciation is: /'taɪdiːbi:/ tai-D-B, etymology: titanium) is an open-source distributed scalable Hybrid Transactional and Analytical Processing (HTAP) database. It features infinite horizontal scalability, strong consistency, and high availability. TiDB is MySQL compatible and serves as a one-stop data warehouse for both OLTP (Online Transactional Processing) and OLAP (Online Analytical Processing) workloads.

  • Horizontal scalability

    TiDB provides horizontal scalability simply by adding new nodes. Never worry about infrastructure capacity ever again.

  • MySQL compatibility

    Easily replace MySQL with TiDB to power your applications without changing a single line of code in most cases and still benefit from the MySQL ecosystem.

  • Distributed transaction

    TiDB is your source of truth, guaranteeing ACID compliance, so your data is accurate and reliable anytime, anywhere.

  • Cloud Native

    TiDB is designed to work in the cloud -- public, private, or hybrid -- making deployment, provisioning, and maintenance drop-dead simple.

  • No more ETL

    ETL (Extract, Transform and Load) is no longer necessary with TiDB's hybrid OLTP/OLAP architecture, enabling you to create new values for your users, easier and faster.

  • High availability

    With TiDB, your data and applications are always on and continuously available, so your users are never disappointed.

For more details, see How we build TiDB.
