Evolution of Feed Data Warehouse Wide-Table Modeling at Baidu App

Baidu’s Mobile Ecology team transformed its Feed data warehouse through three progressive stages—hour‑level core tables, a real‑time wide table, and a unified day‑level multi‑version table—consolidating traffic, content, and user data into a single partitioned wide‑table architecture that resolves granularity inconsistencies, cuts processing cost, and delivers real‑time to daily latency for diverse analytics.

Backend Storage Design for Timeline Feed Streams: Read Diffusion, Write Diffusion, and Hybrid Approaches

Backend storage for timeline feeds can use read‑diffusion (pull), write‑diffusion (push), or a hybrid mix, each with trade‑offs in read/write load, scalability, and storage, while pagination should rely on last_id and snapshots for state‑driven ordering such as live‑streaming feeds.
