Class PatternMixtureGenerator

java.lang.Object

org.apache.pinot.tools.data.generator.PatternMixtureGenerator

All Implemented Interfaces:

Generator

public class PatternMixtureGenerator
extends Object
implements Generator

PatternMixtureGenerator enables combination of multiple Generators in alternating and additive patterns, including nested mixture models. This is typically used to generate similar (but not exact copies of) time series for different dimension values of series or to simulate anomalous behavior in a otherwise regular time series. Generator example:

     generator bins = [
       [ { type = "SEASONAL", mean = 10, ... } ],
       [ { type = "SEASONAL", mean = 30, ... }, { type = "SPIKE", arrivalMean = 2, ... } ],
       [ { type = "SEASONAL", mean = 50, ... } ],
     ]

     returns [ 10, 30, 50, 11, 29, 52, 10, 114, 51, 9, 64, 50, 10, 35, 49, ... ]
