Migrating from a mature database like SQL Server to a domestic alternative such as KingbaseES often raises concerns about performance. This case study shows that with careful planning and optimization, the migration can actually yield a 60% improvement in TPS. The key factors included schema adaptation, index tuning, and query optimization specific to KingbaseES's architecture. The retrospective also highlights the importance of thorough testing and a phased rollout to mitigate risks. For enterprises in China or those seeking to reduce dependency on foreign software, this provides a practical roadmap. The performance gains suggest that KingbaseES is a viable option for high-throughput workloads. However, the success depends heavily on the team's expertise and the specific workload characteristics. This case is a valuable reference for database migration projects.
This retrospective details migrating from SQL Server to KingbaseES (a Chinese domestic database), achieving a 60% TPS improvement. It addresses common fears about performance degradation during such migrations.
