Packages that use ArrayOfItemsSerDe

Package	Description
org.apache.datasketches	This package is the parent package for all sketch algorithms.
org.apache.datasketches.frequencies	This package is dedicated to streaming algorithms that enable estimation of the frequency of occurence of items in a weighted multiset stream of items.
org.apache.datasketches.quantiles	The quantiles package contains stochastic streaming algorithms that enable single-pass analysis of the distribution of a stream of real (double) values or generic items.
org.apache.datasketches.sampling	This package is dedicated to streaming algorithms that enable fixed size, uniform sampling of unweighted items from a stream.
