Case Study: WeBank cuts costs and scales to petabytes with TiDB from PingCAP

WeBank cuts operational costs by 30% with PingCAP

WeBank, China's first digital-only bank, faced significant challenges scaling its data infrastructure to support its massive growth. Its legacy TDSQL architecture struggled with capacity expansion, high concurrency, and cost efficiency, and could not meet its ambitious 99.999% availability goals. To overcome these limitations, WeBank turned to vendor PingCAP and adopted their TiDB distributed SQL database as a foundational solution for its most demanding, mission-critical services.

By implementing PingCAP's TiDB, WeBank built a dual-engine database architecture that combined TDSQL for smaller workloads with TiDB for high-volume systems. This solution provided horizontal scalability, financial-grade availability, and intelligent operations tooling. The results were substantial: WeBank cut operational costs by 30%, achieved 99.999% uptime, and now manages over 1.3 petabytes of data across 80 clusters, with its largest cluster handling 237,000 queries per second.
