Sd-sql server : scalable distributed database system

Abstract EN

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 Sky Server 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.
