Reddit is a social news aggregator designed for hosting community-driven discussions and content sharing through threaded conversations and user-submitted links. It functions as a platform for managing large volumes of user-generated content, providing a structured interface for programmatic access to site data and core application functionality.
The platform utilizes a REST API to expose site data and user interactions to external clients. To maintain performance across large datasets, it employs an external full-text search engine that offloads indexing and query processing from the primary database.
The system architecture incorporates role-based access control to manage permissions and an event-driven message bus to decouple internal components. It also includes a dedicated pipeline for the private reporting and disclosure of security vulnerabilities.
