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.partitions | |
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.

PartitioningFeature.getPartitionBoundariesFromNumParts(int numEquallySizedParts)
This method returns an instance of
GenericPartitionBoundaries which provides
sufficient information for the user to create the given number of equally sized partitions, where "equally sized"
refers to an approximately equal number of items per partition. |

PartitioningFeature.getPartitionBoundariesFromNumParts(int numEquallySizedParts,
QuantileSearchCriteria searchCrit)
This method returns an instance of
GenericPartitionBoundaries which provides
sufficient information for the user to create the given number of equally sized partitions, where "equally sized"
refers to an approximately equal number of items per partition. |
