Compared with the previous database setup, throughput improved by roughly 1.7x, storage usage fell by more than 70 percent, and monthly operating costs dropped by about 40 percent. f4samurai CTO Makoto Morimoto said no performance issues arose during access spikes in the proof of concept.","whyItMatters":"The deal is a cost and scaling story rather than a technology showcase: f4samurai cut monthly database costs by about 40 percent and storage by more than 70 percent without large-scale application refactoring, which is the kind of migration pitch other mobile game operators will now be measured against.","webCardHtml":"\u003cp\u003eThe migration was completed with application-side changes limited to partition setting adjustments and tuning of inter-node communication, using OceanBase\u0026#39;s OMA and OMS data migration tools. f4samurai said backend traffic for the title began to fluctuate significantly day by day as the business expanded, and it wanted stable performance during access spikes without large-scale code changes.\u003c/p\u003e\u003cp\u003eOceanBase can adjust resources online without stopping services, letting f4samurai run a minimal cluster during normal operations and scale up when traffic surges.
