Abstract
A method is disclosed for reorganizing a set of database partitions based on a ranked set of database partitions. The method includes a step to determine a fragmentation indicator for each database partition within a set of database partitions. A step ranks the set of database partitions according to a rank criteria. The rank criteria includes, at a minimum, the fragmentation indicator. A step reorganizes a subset of the database partitions in the ranked set of database partitions. The subset is selected, at least in part, by a rank order for the ranked set of database partitions. The subset may be selected such that ranked database partitions satisfying a reorganization threshold are included in the subset.
