Tencent’s hardware teams evolved from a lack of verification tools in 2019 to building AI inference chips, video‑encoding silicon, and intelligent NICs, overcoming FPGA challenges, scaling cloud infrastructure, and delivering high‑performance, low‑cost solutions for massive multimedia and AI workloads.
The 2021 TencentOS Tiny AIoT Innovation Competition showcased over 50 original projects, including award‑winning multi‑functional pedestrian detection devices, AI‑enhanced smart wheelchairs, and endangered‑animal recognition systems, each demonstrating low‑power embedded AI, edge computing, and cloud integration for diverse real‑world applications.
This article examines the architecture differences between cloud‑native TDSQL‑C and traditional MySQL, outlines TDSQL‑C’s elastic, serverless, low‑latency features, compares MySQL disaster‑recovery models, and details the multi‑dimensional disaster‑recovery system and its cross‑AZ/Region challenges and solutions.
This article presents the architecture, key features, and operational benefits of a cloud‑native ClickHouse OLAP platform, describing how storage‑compute separation, a unified master node, and shared storage reduce cost, improve availability, and simplify management while remaining fully compatible with the open‑source ClickHouse ecosystem.
This article analyzes the limitations of the Linux Completely Fair Scheduler (CFS) for high‑priority workloads, introduces Tencent's custom offline BT scheduler that provides absolute preemption, and presents experimental results showing significant improvements in latency, CPU utilization, and carbon‑reduction for cloud‑native services.
This article explains the role of operating systems in computers and servers, outlines the main server OS families, introduces TencentOS's server, IoT, and edge variants, and details the performance, security, and cloud‑native advantages of TencentOS Server.
This article analyzes the bottlenecks of advertising coarse‑ranking training on the Light framework and presents a series of optimizations—including parallel data download, thread‑queue buffering, integer‑to‑string conversion with fmt, and zlib replacement with czlib—that together achieve up to 58% QPS improvement and notable CPU efficiency gains.
This article explains why code review is critical, outlines its benefits and common difficulties, describes the TDSQL‑C distributed database architecture, and presents a detailed code‑review workflow, author and reviewer responsibilities, commit conventions, and cultural practices to improve software quality and reliability.
The presentation at SACC2021 detailed the background, architecture, performance, reliability, and future development directions of Tencent's cloud‑native distributed database TDSQL‑C, highlighting its compute‑storage separation, serverless elasticity, high QPS capability, and advanced fault‑tolerance mechanisms.
This article analyzes how MySQL slave crashes can cause inconsistencies between master info and relay log positions during sync_master_info and sync_relay_log_info processes, presents case studies of duplicated events, explains the impact of different storage repositories (FILE vs TABLE), and recommends configuration settings to achieve server‑crash‑safe replication.
