The User and Relation Platform team is responsible for building and maintaining a relationship management platform that supports TikTok's extensive operations. This includes the main TikTok product, CapCut, and other offerings within our TikTok product ecosystem.

We manage a wide range of relationship dynamics such as user followership, block relations, and contacts. Our platform handles the reading and writing of this data, delegated to us by our customers.

Our team delivers high-traffic data reading and writing capabilities while offering resilience against degradation and disasters, enforcing data privacy safety controls, and maintaining stability, efficiency, security, and convenience for online business usage.
