发明名称 Dynamic data stream histograms for large ranges
摘要 A method for creating a histogram from a plurality of data elements that includes specifying a plurality of internal buckets, wherein each internal bucket of the plurality of internal buckets represent values between an internal minimum value and an internal maximum value, wherein a plurality of differences of the internal minimum value and the internal maximum value of each internal bucket are heterogeneous, populating the plurality of internal buckets with the plurality of data elements based on the internal minimum value and the internal maximum value of each internal bucket to obtain a plurality of populated internal buckets, and outputting the histogram from the plurality of populated internal buckets.
