Abstract
A database management system obtains key ranges associated with partitions of a database table, and determines that restoration of data associated with at least one of these partitions would take time that is estimated to exceed a goal time. The database management system splits a partition into two or more additional partitions, so that the respective estimated restoration times for data associated with the additional partitions is estimated to be less than the goal time. The database management system then causes the database table to be restored according to partitions that comprises the additional partitions.
