There are many examples of using React's reducers to handle complex model mutation; furthermore there are companion examples showing use of more sophisticated reducers to handle undo/redo support as opposed to a Command based approach (like Stunner).

All of the examples however store the whole (updated) object model in history; i.e. complete snapshots. There are concerns that this approach may be very memory intensive.

This JIRA is to research the feasibility of this approach.
