How Suning’s Big Data Engine Powered a Record‑Breaking 618 Sale

During the 618 shopping festival, Suning launched the "Super Show" event, offering massive subsidies and billions of red‑packet rewards, while its sales grew dramatically across all channels.

The Suning data middle platform recorded more than 200 billion service calls, a daily data processing volume exceeding 38.5 PB , and total computation reaching 31.5 trillion operations, ensuring intelligent shows, precise subsidies, and rich red‑packet experiences.

One month before the event, the foundational platform team rehearsed full‑scenario chains and emergency plans, improving real‑time link speed, stability, and resource efficiency, and enabling the platform to handle over a million concurrent tasks and tens of millions of orderly tasks.

During the live show, Kafka processed more than 80 million TPS of real‑time messages, while HBase sustained over 50 million TPS requests.

The data middle platform optimized over 3,000 core metrics and refined more than 5,000 core models, achieving a 100 % SLA guarantee.

The tag platform conducted full‑link stress tests, with advertising audience service calls surpassing 21.6 billion per day, generating 1.6 × 10⁴ individual audience packages and covering over 500 billion people, while supporting 20,000 daily portrait queries.

Data analysis tools deep‑optimized the OLAP engine, reaching 20 million daily calls and 100 million dimension data service calls, supporting 7,000 reports and more than 3,000 core indicators, serving roughly 300,000 analysts.

All these achievements reflect the dedication of Suning’s IT and big‑data teams, whose relentless effort made every personalized recommendation, consumption decision, and premium experience possible during the post‑pandemic consumer “recovery battle”.
