How Douyin’s Data Asset Platform Revolutionizes Big Data Lineage

Douyin Group’s one‑stop data asset portal shifts the focus from traditional metadata collection to a systematic “manage‑find‑use” data asset platform, aiming to serve users with precise data discovery and utilization across massive business scenarios.

The platform ingests diverse data source metadata into a unified metadata lake, including full‑linkage lineage, and enables secondary operations such as asset registration, classification, and lifecycle management. It also provides asset evaluation, search, portal, recommendation, and AI‑driven search capabilities to meet varied consumption needs.

The primary goal is to construct a comprehensive, real‑time, and accurate big‑data lineage that powers end‑to‑end scenario applications, enhancing efficiency across the organization.

Key motivations for building robust lineage include:

Seeing the chain: With millions of daily ETL tasks, lineage reveals relationships between business processes.

Ensuring quality: Real‑time lineage helps assess the impact of frequent task changes on production.

Guaranteeing security: Lineage tracks the propagation of sensitive data, protecting enterprise information.

Reducing cost: Accurate lineage identifies low‑value resources, guiding optimization and governance.

Thus, establishing a solid big‑data lineage is essential for Douyin’s data governance and operational excellence.
