    Abstract: A method, apparatus, and system for custom policy driven data placement and information lifecycle management in a database management system are provided. A user or database application can specify declarative custom policies that define the movement and transformation of stored database objects. A custom policy defines, for a database object, a custom function to evaluate on an associated database object to determine whether an archiving action is triggered. Archiving actions may include compression, data movement, table clustering, and other actions to place the database object into an appropriate storage tier for a lifecycle phase of the database object. The custom function is defined by the database user, and can flexibly include any customized business logic using data sources internal and external to the database, including database access statistics such as segment level or block level heatmaps.

    Abstract translation: 提供了一种用于数据库管理系统中自定义策略驱动数据放置和信息生命周期管理的方法,装置和系统。 用户或数据库应用程序可以指定定义存储的数据库对象的移动和转换的声明式自定义策略。 自定义策略为数据库对象定义自定义函数,以在关联的数据库对象上进行评估,以确定是否触发归档操作。 归档操作可能包括压缩,数据移动,表集群和其他操作,以将数据库对象放入适用于数据库对象生命周期阶段的存储层。 自定义函数由数据库用户定义,并且可以灵活地包括使用数据库内部和外部的数据源的任何自定义业务逻辑,包括数据库访问统计信息,如段级或块级散热图。
