Packages that use MemorySegmentRequest

Package	Description
org.apache.datasketches.common	This package is for common classes that may be used across all the sketch families.
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.theta	The theta package contains the basic sketch classes that are members of the Theta-Sketch Framework.
