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