The authors introduce the concept of fusible data structures to maintain fault-tolerant data in distributed programs. Given a fusible data structure it is possible to combine a set of such structures into a single fused structure that is smaller than the combined size of the original structures. When any of the original data structures is updated, the fused structure can be updated incrementally using local information about the update and does not need to be entirely recomputed. In case of a failure, the fused structure, along with the correct original data structures, can be used to efficiently reconstruct the failed structure.
