About TiDB
TiDB is a distributed SQL database that is compatible with MySQL. It is built to handle transactions, analytics and vector search in one system, and it can grow by adding more nodes.
What it does
TiDB stores data across many machines while keeping ACID transactions. The same engine can run analytical queries and vector search, so teams do not have to copy data into a separate warehouse or search index for those jobs. The project is open source under the Apache 2.0 licence, and a fully managed cloud service is also offered.
Key features
- ACID transactions across a distributed cluster
- Vector search for AI application data
- Analytics queries on the same data
- MySQL compatible SQL
- Self-managed or fully managed deployment
Who it's for
Backend teams that have outgrown a single MySQL server, and AI application teams that want vector search next to transactional data. Startups that plan for elastic scale may also find it a good fit.
Pricing and good to know
The open source edition is free to use under its licence. The managed TiDB Cloud service has its own plans, which are listed on the pricing page. Running a distributed cluster takes more operational work than a single database server, so small projects may prefer a simpler setup at first.
