Tencent Distributed SQL (TDSQL) is a distributed database product created by Tencent. It possesses features such as strong consistency and high availability, global deployment architecture, distributed horizontal scaling, high performance, and enterprise-level security. It also provides supporting facilities like intelligent DBA, automated operations, and monitoring alarms, offering customers a complete distributed database solution. Currently, TDSQL has provided public and private cloud services to over 500 government and enterprise customers and financial institutions, covering sectors such as banking, insurance, security, internet finance, billing, third-party payment, IoT, internet plus, and government service. With its high-quality product and service, TDSQL has obtained multiple international and national certifications and gained widespread recognition from both customers and the industry. The newly launched version is a new product form of TDSQL, based on the self-developed TDStore engine. Compared to the existing distributed version, it has less intrusion on applications (no need to explicitly specify distribution keys), and both compute and storage can be flexibly scaled on demand without affecting business. Due to technical architecture reasons, the product form has significant changes compared to the existing version. To avoid impacting existing products and specifications, an additional product family definition is required.
