> IndexRegionObserver maintains an in memory state to correctly generate
> mutations for concurrent updates to the same row. These mutations hold
> references to cells which can be backed by off-heap memory. It is not safe to
> access these cells later as that memory can be reclaimed or reused. The copy
> constructor of the Mutation class doesn't copy the cells.
