Abstract
A method, system, and computer program product provides improved performance for queries on local partitioned indexes. A method of performing a database query comprises receiving a query of spatial data in a database, the database comprising at least one partitioned spatial index, obtaining metadata relating to all partitions of the spatial index using array-fetching techniques, determining, for each partition, whether the partition is relevant to the query by comparing with 'footprint' (root_mbr) information stored in the metadata for the partition, and processing the query on each relevant partition.
