 Abstract: We present SD-SQL Server, a prototype scalable distributed database system. It let a relational table to grow over new storage nodes invisibly to the application. The evolution uses splits dynamically generating a distributed range partitioning of the table. The splits avoid the reorganization of a growing database, necessary for the current DBMSs and a headache for the administrators. We illustrate the architecture of our system, its capabilities and performance. The experiments with the well-known SkyServer database show that the overhead of the scalable distributed table management is typically minimal. To our best knowledge, SD-SQL Server is the only DBMS with the discussed capabilities at present.
