Merging What's Cracked, Cracking What's Merged: Adaptive Indexing in Main-Memory Column-Stores

Summary: Introduces hybrid adaptive-indexing algorithms for main-memory column stores that combine cracking’s low startup cost with merging’s rapid convergence. Experiments show near-ideal query overhead and refinement, outperforming prior adaptive and conventional indexes. (summarized by gpt-5.6-luna on Jul 24 2026)
