You can use a single partition scheme to partition multiple objects.Ĭreate or alter a table or index and specify the partition scheme as the storage location, along with the column that will serve as the partitioning column. You can use a single partition function to partition multiple objects.Ĭreate a partition scheme that maps the partitions of a partitioned table or index to one filegroup or to multiple filegroups. In nearly all scenarios, you will achieve all benefits of partitioning whether or not you use multiple filegroups.Ĭreate a partition function that maps the rows of a table or index into partitions based on the values of a specified column. If this is not required, you may choose to assign all partitions to a single filegroup, using either an existing filegroup, such as PRIMARY, or a new filegroup with related data file(s).

The main reason to place partitions on multiple filegroups is to ensure you can independently perform backup and restore operations on filegroups. Optionally create a filegroup or filegroups and corresponding data files that will hold the partitions specified by the partition scheme. Partitioning can make large tables and indexes more manageable and scalable.Ĭreating a partitioned table or index typically happens in three or four parts: The data in partitioned tables and indexes is horizontally divided into units that can be spread across more than one filegroup in a database, or stored in a single filegroup. You can create a partitioned table or index in SQL Server, Azure SQL Database, and Azure SQL Managed Instance by using SQL Server Management Studio or Transact-SQL.
