Data Source Partitions

You use the Profiles resource to create partitioned data sources. Commerce Server 2002 supports data source partitioning to accommodate site traffic that can exceed 25 million SQL Server users, and 10 million Active Directory users.

Partitioning is an effective means to scale and maintain the database transaction loads associated with large populations of users. Each partition of a data source can connect to a database or a Lightweight Directory Access Protocol (LDAP) source.

All of the partitions for a single data source must connect to the same type of data storage (OLE DB database or LDAP source), and all data stores mapped to the partitions of a single data source must have the same schema.

With a partitioned data source, the individual databases offer better performance and response times than if all of the data collected with a profile definition is stored in a single database.
