Designing a Differentiated DSP Near‑Real‑Time Data Warehouse with Flink, DLF Paimon, and EMR Serverless StarRocks

The DSP advertising data pipeline was re‑architected by splitting three distinct links—NRR, BT, and CT—and assigning DLF Paimon for massive low‑frequency data, EMR Serverless StarRocks primary tables for high‑value low‑latency queries, and unified service‑layer merging, achieving 2‑minute freshness, sub‑5 ms point queries, ~60% storage cost reduction, and improved fault isolation.
