Returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator's sequence. The general contract of nextDouble is that one double value, chosen (approximately) uniformly from the range 0.0d (inclusive) to 1.0d (exclusive), is pseudorandomly...
The way partitions are managed is that each partition is assigned a roughly equal slice out of the range of partition key values; therefore you are advised to choose a partition key which is relatively random or evenly-distributed. Otherwise, some partitions will see substantially more requests (...

For example, let's create a set generator where the number of elements is random between 0 and ten. Gen<String> elemGen = StrGen.letters(5, 10); Gen<Set<String>> setGen = IntGen.arbitrary(1,10) .then(size -> SetGen.of(elemGen,size)) Do notice that the size is determined at...
