    摘要: Systems and methods for generating dynamic sparse exponential histograms. The system includes a network-based service and a data compression engine to generate a sparse exponential histogram (SEH) representation of a distribution of a plurality of data values of a performance metric of the network-based service. The data compression engine is configured to, map each data value to a bin of an exponential histogram. Responsive to a determination that the mapped bin is not indicated in the SEH representation and that a bin quantity limit would be exceeded by adding the mapped bin, the data compression engine is configured to increase a bin size parameter by a scaling factor to expand data value ranges of the bins, merge bins indicated in the SEH representation according to the expanded data value ranges to reduce the quantity of bins indicated in the SEH representation, and indicate the scaling factor in the SEH representation.
