High-Throughput Event Ingestion & Processing Service (PHP)

Designed to process high-frequency viewer events in near real-time, this system transforms raw activity streams into reliable session analytics at scale. Built around a stateless API and time-windowed session logic, the system ensures accurate, near real-time analytics while maintaining resilience under load. The architecture emphasizes scalability, fault isolation, and extensibility, with clear separation between ingestion, processing, and persistence layers—enabling independent scaling and reliable handling of large event volumes.
