Tencent Games developed a real-time event-driven analytics system using ScyllaDB and Apache Pulsar, leveraging Command and Query Responsibility Segregation (CQRS) and event sourcing patterns to enhance efficiency in monitoring gameplay activities. This architecture enables the seamless handling of large-scale data events by separating data models for reads and writes, allowing independent scaling and reducing conflicts across different teams. ScyllaDB plays a crucial role in efficiently dispatching events to numerous gameplay sessions by using session IDs as partition keys and event IDs as clustering keys, addressing the challenges of event consistency and data distribution. The system simplifies global data management through data replication across keyspaces, facilitating compliance with data protection laws and eliminating the complexities of implementing distributed systems. By utilizing keyspaces as data containers, Tencent ensures transparency and improves the auditability of data distribution while maintaining scalability and efficiency. This innovative approach allows the company to address risks such as cheating activities and harmful content, ensuring a seamless gaming experience for millions of players worldwide.
