Persistence in massively multiplayer online games

摘要: The most important asset of a Massively Multiplayer Online Game is its world state, as it represents the combined efforts and progress all participants. Thus, extremely that this state not lost in case server failures. Survival typically achieved by making persistent, e.g., storing relational database. main challenge approach to track large volume modifications applied real time. This paper compares variety strategies persist changes game world. While critical events must be written synchronously persistent storage, set approximation are discussed compared suitable for with low consistency requirements, such player movements. An analysis better understand possible limitations bottlenecks these presented using experimental data from an MMOG research framework. Our shows distance-based solution offers scalability efficiency required large-scale games well offering error bounds eliminating unnecessary updates associated localized movement.
