Interval Partitioning是Oracle数据库中一种表分区技术,它根据一个时间间隔来动态地创建和管理分区。Interval Partitioning可以自动为新插入的数据创建新的分区,无需手动创建分区。 应用场景: 时间序列数据存储:对于包含时间戳的数据表,可以使用Interval Partitioning按照时间间隔对数据进行分区存储,便于对历史数据的管理和查询。
在11G的版本中的Interval Partition不再需要DBA去干预新分区的添加,Oracle会自动去执行这样的操作,减少了DBA的工作量。Interval Partition是Range分区的一个扩展。 1、Extended Composite Partitioning In previous releases of Oracle, composite partitioning was limited to Range-Hash and Range-List partitioning. Oracle...
oracle 11g分区表新特性---interval分区 的坑 oracle 11g的范围分区表中新增的interval分区特性,此种范围分区不需要定义MAXVALUE,Oracle会根据分区定义的步长来动态的分配新分区来容纳超过范围的数据。 解决了原本的范围分区需要手工编写job来预分配分区的问题,但是其分区名时自动命名的。 所以,对于间隔分区 interval(num...
