The key idea is to operate a grid histogram in an approximately rank-transformed space, where the data points are more uniformly distributed and each grid slice contains only a small number of points. Then, the points of each slice are summarised again using the same technique. As each query box partially intersects only few slices and each grid slice has few data points, the summary is able to achieve tight error guarantees. In experiments and through analysis of non-asymptotic formulas we show that SliceHist is not only competitive with existing heuristics in terms of performance, but additionally offers tight error guarantees.http://creativecommons.org/licenses/by/4.0/1595-16062021 IEEE 37th International Conference on Data Engineering Shekelyan Michael Dignös, Anton 1983- Gamper Johann Garofalakis Minos Γαροφαλακης Μινως Institute of Electrical and Electronics Engineers Histograms Conferences Distributed databases Reliability engineering Data engineering
