About SPD Server Cluster Tables

The SAS Scalable Performance Data (SPD) Server enables you to create dynamic cluster tables. A dynamic cluster table is two or more SPD Server tables that are virtually concatenated into a single entity, using metadata that is managed by the SPD Server. Dynamic cluster tables can be used as the inputs or outputs in SAS Data Integration Studio jobs.
Before you can create a cluster table, the following prerequisites must be satisfied:
  • Administrators must have installed, started, and registered an SPD Server. The application server that executes the cluster table job must be able to access the SPD Server. For more information about SPD Servers, see the chapters about common data sources in the SAS Intelligence Platform: Data Administration Guide.
  • An SPD Server library must be available. For more information about SPD Server libraries, see the chapters about common data sources in the SAS Intelligence Platform: Data Administration Guide.
  • All of the source tables that are to be added to a cluster table have been registered in the SPD Server library. All source tables must have the same column structure.
  • A cluster table has been registered in the SPD Server library. The cluster table and all of its source tables must have the same column structure. One way to ensure that all of these tables have the same columns is to use the New Table wizard to copy the metadata from a source table and save it as the metadata for the cluster table. For details about using the New Table wizard, see Registering New Tables with the New Table Wizard.
