Bouros, Panagiotis (author), Titkov, Artur (author), Christodoulou, G.C. (author), Rauch, Christian (author), Mamoulis, Nikos (author)A wide range of applications manage interval data. HINT was recently proposed to hierarchically index intervals in main memory. The index outperforms competitive structures by a wide margin, but under its current setup, HINT is able to service only single query requests. In practice however, real systems receive a large number of queries at...conference paper 2024
