Technical Sharing on Tencent Cloud's CynosDB: Architecture, High Availability, and Distributed Storage

Tencent Cloud’s self‑developed database CynosDB is the first domestically produced cloud‑native database that is compatible with both MySQL and PostgreSQL, offering high availability, pay‑as‑you‑go pricing and elastic scaling that free developers from operational concerns.

The Cloud+ Community technical salon provides a comprehensive analysis of CynosDB, unveiling its internal architecture, including the primary‑multiple‑read design, high‑availability and fast‑recovery mechanisms, computable intelligent storage, and distributed storage concepts.

Topic 1 – CynosDB Technical Internals – New Generation Compute Engine : Explores the cloud‑native compute‑storage separation architecture, detailing how storage and compute are decoupled to improve performance, scalability and availability.

Topic 2 – Computable Intelligent Storage Revealed : Describes CynosDB’s log‑as‑data approach, where logs are sunk into a backend distributed storage layer, reducing network traffic and enhancing scalability and reliability.

Topic 3 – CynosDB High‑Availability Architecture and Fast Recovery : Explains how CynosDB for MySQL achieves instance high availability and lowers recovery time objective (RTO) in a compute‑storage separated setup.

Topic 4 – CynosDB for PostgreSQL Primary‑Multiple‑Read Architecture : Covers the design of one‑primary‑multiple‑read in a shared‑storage environment, highlighting differences from traditional PostgreSQL replication.

Topic 5 – CynosDB for PostgreSQL Distributed Storage (CynosStore) : Introduces CynosStore as the distributed storage foundation, presenting its asynchronous log‑based file system with multi‑replica, high availability, multi‑tenancy and auto‑scaling capabilities.

Event details: Saturday, March 16 2019, 13:30‑18:00, at the Beijing University of Posts and Telecommunications Technology Hotel, second‑floor multifunction hall. Free registration via QR code or by clicking “Read Original”.
