This sketch provides a reservoir sample over an input stream of items.
Class to union reservoir samples of generic items.
This sketch provides a reservoir sample over an input stream of longs.
Class to union reservoir samples of longs.
A simple object o capture the results of a subset sum query on a sampling sketch.
This class provides access to the samples contained in a VarOptItemsSketch.
This sketch provides a variance optimal sample over an input stream of weighted items.
Provides a unioning operation over varopt sketches.
This package is dedicated to streaming algorithms that enable fixed size, uniform sampling of unweighted items from a stream.
These sketches are mergeable and can be serialized and deserialized to/from a compact form.
