TiDB is a distributed SQL database that is compatible with MySQL. It handles transactional (OLTP) and analytical (OLAP) workloads on the same data, without separate systems or ETL pipelines. The database scales horizontally with automatic sharding, offers ACID consistency and has native vector indexing for search and RAG applications. Internally, TiDB consists of the TiKV row store and the TiFlash column store. You can operate TiDB yourself (TiDB Self-Managed) or use it as the managed TiDB Cloud service, available on AWS, Google Cloud, Microsoft Azure and Alibaba Cloud.
TiDB is open source under the Apache 2.0 licence. Its developer PingCAP was founded in Beijing in 2015 and is now headquartered in Sunnyvale, California (US), with offices in Singapore, Kuala Lumpur and Tokyo. The documentation does not name specific regions or European locations for TiDB Cloud. Organisations that want to keep data within the EU can install TiDB themselves on their own or European infrastructure, where the source code is freely available, while the managed service is delivered by a US provider.
