> 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.
