Class PatternSequenceGenerator

java.lang.Object

org.apache.pinot.tools.data.generator.PatternSequenceGenerator

All Implemented Interfaces:

Generator

public class PatternSequenceGenerator
extends Object
implements Generator

PatternSequenceGenerator produces a series of sequentially increasing (decreasing) numbers, optionally with a fixed number of repetitions per values. This pattern is typical for monotonically increasing series such as timestamps. Generator example:

     start = -10
     stepsize = 3
     repetitions = 2

     returns [ -10, -10, -7, -7, -4, -4, -1, -1, 2, 2, ... ]

• ./pinot-tools/src/main/resources/generator/complexWebsite_generator.json
