Abstract
A first plurality of replicated state machines may execute a sequence of ordered agreements to make mutations to a data stored in a first data storage service of a first type. A second plurality of replicated state machines may execute the sequence of ordered agreements to make mutations to the data stored in a second data storage service of a second type. First metadata of the mutated data stored in the first data storage service may then be received and stored, and second metadata of the mutated data may be stored in the second data storage service. The stored first and second metadata may then be compared when the data have settled, and a selected action carried out based upon the result of the comparison.
