Packages that use QuantilesSketchIterator
Package
Description
org.apache.datasketches.kll
This package is for the implementations of the sketch algorithm developed by Zohar Karnin, Kevin Lang, and Edo Liberty that is commonly referred to as the "KLL" sketch after the authors' last names.
org.apache.datasketches.quantiles
The quantiles package contains stochastic streaming algorithms that enable single-pass analysis of the distribution of a stream of quantiles.
org.apache.datasketches.quantilescommon
This package contains common tools and methods for the quantiles, kll and req packages.
org.apache.datasketches.req
This package is for the implementation of the Relative Error Quantiles sketch algorithm.
