All Packages
| Package | Description |
|---|---|
| org.apache.datasketches |
This package is the parent package for all sketch algorithms.
|
| org.apache.datasketches.cpc |
Compressed Probabilistic Counting
|
| org.apache.datasketches.fdt | |
| 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.hash |
The hash package contains a high-performing and extended Java implementation
of Austin Appleby's 128-bit MurmurHash3 hash function originally coded in C.
|
| org.apache.datasketches.hll |
The hll package contains a high performance implementation of Phillipe
Flajolet's HLL sketch with significantly improved error behavior.
|
| org.apache.datasketches.hllmap |
The hllmap package contains a space efficient HLL mapping sketch of keys to approximate unique
count of identifiers.
|
| org.apache.datasketches.kll | |
| 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.req | |
| org.apache.datasketches.sampling |
This package is dedicated to streaming algorithms that enable fixed size, uniform sampling of
unweighted items from a stream.
|
| org.apache.datasketches.theta |
The theta package contains all the sketch classes that are members of the
Theta Sketch Framework.
|
| org.apache.datasketches.tuple |
The tuple package contains implementation of sketches based on the idea of
theta sketches with the addition of values associated with unique keys.
