SQL Server, Azure SQL Database, and Azure SQL Managed Instance support table and index partitioning. The data of partitioned tables and indexes is divided into units that may be spread across more than one filegroup in a database or stored in a single filegroup. When multiple files exist i...
Partitioning makes large tables or indexes more manageable by letting you access or manage subsets of data quickly and efficiently, while maintaining the integrity of the overall collection. By default, SQL Server supports up to 15,000 partitions. For more information, seePartitioned Tables and ...
By treating partitioned tables as indexes, SQL Server 2008 can frequently use much simpler query plans. Let's look at the SQL Server 2008 plan for the above example: |--Table Scan(OBJECT:([T])) This query plan is no different than what you might see if you scanned any other ordinary...
摘要:SQL Server 表分区 正文: 可伸缩性性是数据库管理系统的一个很重要的方面,在SQL Server 2005中可伸缩性方面提供了表分区功能。 其实对于有关系弄数据库产品来说,对表、数据库和服务器进行数据分区的从而提供大数据量的支持并不是什么新鲜事,但SQL Server 2005提供了一个新的体系结构功能,用于对数据库中的文...

Each partition was created and managed separately and views were used to simplify access; however, this solution yielded few performance gains. When a UNIONed view existed to simplify user and application access, the query processor had to access every underlying table in order to determine what ...
