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.

"WebbSee Algorithm 1. The binning sketch algorithm performs the pre-binning process using equal-frequency interval binning. To do so, first, the internal sketch corresponding to event and non-event records are combined (mergeability) as a single sketch accounting for all data. Subsequently, \(b - 1\) quantiles (split points \(s\)) are computed to ... " - Sketch algorithms

Webbused algorithms such as Count-Min, Count-Median and Count-Sketch. Informally, these algorithms hash data items into Bbuckets, count the number of items hashed into each bucket, and use the bucket value as an estimate of item frequency. The process can be repeated using multiple hash functions to improve accuracy. WebbMoreover, count-min sketch is parallelizable if we rarely have collisions, which means that we may need a “taller” table (i.e., more hash functions). Conclusion. This story examines …
