Fan Xinxin (NetEase Yishu Big Data Development Expert) delivered a talk titled "Building an Efficient Data Lake with Apache Iceberg," explaining the limitations of traditional Lambda architecture, the benefits of incremental computation, Iceberg's core principles, and practical challenges encountered at NetEase.

Liu Yufei (Didi Senior Development Engineer) presented "Flink in Didi's Real‑Time Computing Practice," outlining Didi's evolution from ad‑hoc clusters to a unified Flink platform, the role of meta‑construction, custom schedulers, and the scale of the real‑time cluster (over 1,300 machines running more than 12,000 jobs).

Zeng Bin (Youzan Data Growth Technology Lead) discussed data‑driven growth, stressing that growth is achieved through capability improvement and cognitive upgrades, and how Youzan empowers merchants with data‑based growth tools.
