TiDB ("Ti" stands for Titanium) is an open-source NewSQL database that supports Hybrid Transactional and Analytical Processing (HTAP) workloads. It is MySQL compatible and features horizontal scalability, strong consistency, and high availability.

  1. Horizontal Scalability

  2. MySQL Compatible Syntax

  3. Distributed Transactions

  4. Cloud Native

  5. Minimize ETL

  6. High Availability

TiDB expands both SQL processing and storage by simply adding new nodes. This makes infrastructure capacity planning both easier and more cost-effective than traditional relational databases which only scale vertically.

TiDB acts like it is a MySQL 5.7 server to your applications. You can continue to use all of the existing MySQL client libraries, and in many cases, you will not need to change a single line of code in your application. Because TiDB is built from scratch, not a MySQL fork, please check out the list of known compatibility differences.

TiDB internally shards table into small range-based chunks that we refer to as "Regions". Each Region defaults to approximately 100 MiB in size, and TiDB uses an optimized Two-phase commit to ensure that Regions are maintained in a transactionally consistent way.

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