VEGA: An Active-tuning Learned Index with Group-Wise Learning Granularity

Summary: VEGA uses active-tuning with group-wise granularity to simplify distribution and tighten lookup bounds. A memory-budget framework merges key grouping with online key repositioning to achieve strong theory and empirical lookup/build performance. (summarized by gpt-5-nano on Feb 09 2026)
