Using Table and Index Partitioning

Data can be stored by using the storage algorithms provided by Tables et index partitionnés. Partitioning can make large tables and indexes more manageable and scalable.

Index and Table Partitioning

The feature enables index and table data to be spread across multiple file groups in partitions. A partition function defines how the rows of a table or index are mapped to a set of partitions based on the values of certain columns, referred to as partitioning columns. A partition scheme maps each partition specified by the partition function to a file group. This lets you develop archiving strategies that enable tables to be scaled across file groups, and therefore physical devices.

The Database object contains a collection of PartitionFunction objects that represent the implemented partition functions and a collection of PartitionScheme objects that describe how data is mapped to file groups.

Each Table and Index object specifies which partition scheme it uses in the PartitionScheme property and specifies the columns in the PartitionSchemeParameterCollection.
