This is the core Java component of the DataSketches library. It contains all of the sketching algorithms and can be accessed directly from user applications. This component is also is a dependency of other components of the library that create adaptors for target systems, such as Hadoop Pig and Hadoop Hive. Please refer to our website for more comprehensive information about the various sketching algorithms and how to use them.
Note that we have a parallel core component for C++ and Python implementations of the same sketch algorithms, incubator-datasketches-cpp.
