PartitionReplicaStateChecker	Verifies up-to-dateness of each of partition replicas owned by this member.
PartitionStateManager	Maintains the partition table state.

Package com.hazelcast.internal.partition.impl Description

Contains the actual implementation of the InternalPartitionService. It is very important that should be the least amount of dependencies to this package. Preferably only the InternalPartitionServiceImpl is called while constructing an instance and after that all communication should go through the InternalPartitionService interface. Nobody needs to know about the actual implementing classes because this gives a very tight coupling and this is undesirable. This is not only undesirable for external people because they could easily be tightly coupled to the internals of Hazelcast, but it also is undesirable for us because it becomes a tangled mess that prevent easy replacement/changes.
