> Currently there are three data structures that are considered as first class 
> citizens in Giraph: PartitionStore, MessageStore, and EdgeStore. However, in 
> some applications mutations can be large/massive, so mutations should also be 
> part of the data that out-of-core mechanism keeps an eye on. For this reason, 
> first, there is a need to add MutationStore as one of the first class 
> citizens amongst data-heavy structures in Giraph. Second, we should add a 
> disk-backed mutation store to have mutations as part of data out-of-core 
> mechanism deals with.
