Apache DataSketches (incubating)

A software library of stochastic streaming algorithms

Apache DataSketches is an open source, high-performance library of stochastic streaming algorithms commonly called “sketches” in the data sciences. Sketches are small, stateful programs that process massive data as a stream and provide approximate answers, with mathematical guarantees, to computationally difficult queries orders-of-magnitude faster than traditional, exact methods.

After 8 years of development and 5 years as in Open Source, we have begun the important migration from a stand-alone GitHub site to being a member of the Apache Software Foundation community. While we undergo this migration, we beg your patience.

As the repositories under GitHub.io/DataSketches migrate they will disapear from the the GitHub.com/DataSketches organization page. Please refer to this list be directed to the new locations.

Note The following names in BOLD are of the old github.com/datasketches/ organization repositories.

Web Site and Web Site Source
- datasketches.github.io moved to datasketches.apache.org
- github.com/DataSketches/DataSketches.github.io moved to github.com/apache/incubator-datasketches-website
Java Core
- sketches-core moved to incubator-datasketches-java This is the core library that contains all sketch algorithms written in Java.
- memory moved to incubator-datasketches-memory Low-level component used by other java components.
Java Adaptors
- sketches-hive moved to incubator-datasketches-hive Adapts the Java core to Apache Hive.
- sketches-pig moved to incubator-datasketches-pig Adapts the Java core to Apache Pig.
- sketches-vector moved to incubator-datasketches-vector Experimental sketches for vector and matrix processing.
- Apache Druid adaptors
C++ / Python Core
- sketches-core-cpp moved to incubator-datasketches-cpp This is the core library that contains all major sketch algorithms written in C++ and Python.
C++ Adaptors
- sketches-postgres moved to incubator-datasketches-postgresql Adapts the C++ core to PostgreSQL.
Java and C++
- characterization moved to incubator-datasketches-characterization Java and C++ Characterization suites for benchmarking and exhaustive testing.
Obsolete Components
- sketches-android An experimental proof-of-concept sketch for the Android cell-phone.
- sketches-misc
- experimental
- characterization-cpp
- experimental-cpp
Command Line Functions (Mostly obsolete. These may move to Apache later or replaced by Python)

Disclaimer: Apache DataSketches is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
