WebbThe Theta Sketch Framework (TSF) is a mathematical framework defined in a multi-stream setting that enables set expressions over these streams and encompasses many different sketching algorithms. A rudimentary introduction to the mathematics of the simpler sketch algorithms is developed in the Theta Sketch Equations document. WebbSketching algorithms like this one are the heart of many stream processing applications for good reason. Sketches can produce estimates of configurable quality, require requires sub-linear space and often do not need to store identifiers. This makes them an attractive option for counting a large number of distinct items with relatively little ...

Webb6 sep. 2024 · Fortunately there are plenty of quantile sketching algorithms available including the GK-sketch, the t-digest, the HDR histogram, and the Moments sketch that we looked at last year. For reasons we’ll see shortly though, none of those were good enough for Datadog, so they developed their own sketching data structure, DDSketch. hi siri what are you doing
