Implementing PartitionAware allows one to override the default partitioning scheme.
Instead of using the keys themselves to spread the data around the cluster the
key contained in partitionKey is used.
This provides the user with an ability to contain related keys within the same
partition and, consequently, within the same node.
In Hazelcast, disparate data structures will be stored on the same partition,
based on the partition key. For example, if "Steve" was used, then the following
would be on one partition.
a customers IMap with an entry of key "Steve"
an orders IMap using a customer key type implementing PartitionAware with key "Steve"
any queue named "Steve"
any PartitionAware object with partition key "Steve"
