HINT: A Hierarchical Index for Intervals in Main Memory
Summary: HINT is an in-memory, hierarchical interval index for overlap queries, using a partitioning scheme that assigns each interval to at most two partitions per level and splits by begin-inside vs begin-before boundaries. Space-efficient storage handles sparsity and skew; experiments show an order of magnitude faster overlap queries than prior approaches on real and synthetic data.
