Examples of com.yahoo.ycsb.generator.ExponentialGenerator

com.yahoo.ycsb.generator.ExponentialGenerator
A generator of an exponential distribution. It produces a sequence of time intervals (integers) according to an exponential distribution. Smaller intervals are more frequent than larger ones, and there is no bound on the length of an interval. When you construct an instance of this class, you specify a parameter gamma, which corresponds to the rate at which events occur. Alternatively, 1/gamma is the average length of an interval.

    {
                    double percentile = Double.parseDouble(p.getProperty(ExponentialGenerator.EXPONENTIAL_PERCENTILE_PROPERTY,
                                                                         ExponentialGenerator.EXPONENTIAL_PERCENTILE_DEFAULT));
                    double frac       = Double.parseDouble(p.getProperty(ExponentialGenerator.EXPONENTIAL_FRAC_PROPERTY,
                                                                         ExponentialGenerator.EXPONENTIAL_FRAC_DEFAULT));
                    keychooser = new ExponentialGenerator(percentile, recordcount*frac);
    }
    else
