TDSQL Boundless is a new generation distributed database developed in-house by Tencent Cloud. As a key member of the TDSQL family, it effectively solves the complexity challenges of traditional distributed databases through its transparent distributed architecture and elastic scalability. This enables your enterprises to focus on business innovation instead of wrestling with the complex data architectures, while providing enterprise-grade high availability and security, delivering reliable support for critical business systems.

Key Features

Multi-Master Writes & Seamless Scaling

TDSQL Boundless features a multi-master architecture where every node can handle write operations, dramatically increasing total throughput. The platform scales linearly and transparently with zero downtime, growing smoothly from a minimal two-node instance to several hundred nodes. Whether handling peak order volumes during an e-commerce sale or high-concurrency interactions in a live stream, TDSQL Boundless manages the load effortlessly. At the same time, its storage engine delivers high data compression, enabling significant cost savings for massive datasets.

Higher Resource Utilization, Lower Costs

TDSQL employs a peer-to-peer architecture where all nodes are active. This eliminates the resource waste common in traditional MySQL primary-replica setups, where secondary nodes often sit idle. Its storage engine, built on an LSM-Tree architecture with intelligent compression, achieves a far higher data compression ratio than traditional engines, leading to a significant reduction in storage costs.

Zero Data Loss & Flexible Disaster Recovery

TDSQL Boundless delivers enterprise-grade reliability. Through multi-replica disaster recovery and automatic failover mechanisms, it ensures zero data loss (RPO=0) and high service availability. The system's built-in resilience allows it to recover from node failures quickly and automatically, with no manual intervention required. Furthermore, it offers flexible deployment models-including 1 AZ, 2 AZ, and 3 AZ setups-to meet your specific disaster recovery requirements.

High Compatibility with MySQL & HBase

TDSQL Boundless is highly compatible with most general features of MySQL, including protocol, syntax, and its broader ecosystem of tools. It also offers compatibility with the HBase API. This means existing MySQL applications can migrate to TDSQL Boundless without code modifications while significantly reducing migration costs and risks.

Automated Data Scheduling for Access Locality

TDSQL Boundless employs advanced "data affinity scheduling" technology that intelligently arranges primary keys, indexes, and related table data on the same node. This transforms complex distributed transactions into simple, single-node operations, not only enhancing performance but also ensuring data consistency.
