Building Permissions into Data Modeling

Explore a 14-minute conference talk from USENIX PEPR '24 on building permissions into data modeling for complex social network applications. Discover how Meta tackles the challenge of managing complicated permission checks across thousands of user actions. Learn about a design pattern that incorporates permissions into data models through three key components: a rules engine for modeling permission logic, integration with the data modeling layer for flexible abstraction, and integration with the data fetching layer for conditional loading. Gain insights into how this approach has improved reliability and performance of permission checks across numerous Meta products. Understand the complexities of implementing permission systems for actions like posting on friends' timelines, changing group cover photos, and messaging marketplace sellers.
