DGFIndex for Smart Grid: Enhancing Hive with a Cost-Effective Multidimensional Range Index

Summary: DGFIndex is a grid-file MDRQ index for Hive; partitions the data space into cubes and stores only cube metadata. Precomputes cube aggregations and uses boundary accesses to speed queries; 2-75x faster aggregation and disk-space savings vs Hive scans. (summarized by gpt-5-nano on Feb 09 2026)
