public class SimplePartitionKey
SimplePartitionKey is a trivial PartitionAwareKey
implementation.
This key could also be used in conjunction with CompositeKey
explicitly associate a partition with custom keys. For example:
new CompositeKey(SimplePartitionKey.getPartitionKey(nPartition), oKeyNatural);
