  • Import/export and repartitioning of partitioned objects
    Patent number: 6820095
    Abstract: An object, such as a relational database table, is partitioned into a plurality of subsets. Selected subsets, e.g. partitions, of the object are exported into a dump file, identifying each exported subset of data by writing a marker in the dump file. Selected subsets are imported from the dump file, by determining whether the marker in the dump file corresponds to the selected subsets, then conditionally importing the data associated with the marker. Objects are repartitioned by exporting the some of the subsets, reconfiguring the object, and importing the exported subsets back into the object.
