How Meipai Scaled Its Live‑Streaming Bullet Screen to Support Millions of Concurrent Users

Meipai's live‑streaming bullet‑screen service was launched in early 2016 and has continuously evolved to support massive user growth, eventually handling millions of concurrent online users. The architecture progressed from a quickly built first version to a robust, scalable system designed for high‑traffic scenarios.

One notable milestone was the TFBOYS live debut on Meipai in June 2016, which attracted 28.6 million viewers across four sessions, generated 2.623 billion likes and 29.8 million comments, illustrating the extreme read/write and interaction load the platform must sustain.

The core technical challenge discussed is how to maintain high‑throughput read/write operations while ensuring overall service stability under such load. The presentation outlines the complete technical stack, design decisions, and incremental improvements that enabled the system to meet these demands.

The speaker, Wang Jingbo, is a senior technical manager at Meitu. He joined the company in September 2015, works in the architecture platform team, and is responsible for core services such as the bullet‑screen system, feed service, task scheduling, and a big‑data‑based quality monitoring framework. With over a decade of backend development experience, he brings extensive practical knowledge of building high‑availability, high‑concurrency internet services.

The session includes detailed architecture diagrams and design insights captured in a series of PPT slides (illustrated by the images below).
