HERMIT in Action: Succinct Secondary Indexing Mechanism via Correlation Exploration
Summary: HERMIT exploits soft functional dependencies to avoid redundant secondary indexes, routing key lookups through correlated-column indexes. Its ML-enhanced TRS-TREE models correlations and outliers, reducing index space and maintenance cost with limited query-time overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
