We present a scalable distributed database system called SD-SQL Server. Its original feature is dynamic and transparent repartitioning of growing tables, avoiding the cumbersome manual repartitioning that characterize current technology. SD-SQL Server re-partitions a table when an insert overflows existing segments. With the comfort of a single node SQL Server user, the SD-SQL Server user has larger tables or gets a faster response time through the dynamic parallelism. We present the architecture of our system, its implementation and the performance analysis. We show that the overhead of our scalable table management should be typically negligible.
