voldemort.performance.benchmark.generator.ScrambledZipfianGenerator
A generator of a Zipfian distribution. It produces a sequence of items, such that some items are more popular than others, according to a Zipfian distribution. Unlike @ZipfianGenerator, this class scatters the "popular" items across the item space. Use this, instead of @ZipfianGenerator, if you don't want the head of the distribution (the popular items) clustered together.

            keyGenerator = new UniformIntegerGenerator(0, keySpace - 1);


        } else if(recordSelection.compareTo(Benchmark.ZIPFIAN_RECORD_SELECTION) == 0) {


            int expectedNewKeys = (int) (opCount * writeProportion * 2.0);
            keyGenerator = new ScrambledZipfianGenerator(recordCount + expectedNewKeys);


        } else if(recordSelection.compareTo(Benchmark.LATEST_RECORD_SELECTION) == 0) {


            keyGenerator = new SkewedLatestGenerator(insertKeySequence);
