Abstract
A system and method for hierarchical synchronization of tiles between a first dataset and a second dataset by computing and storing multiple composite cluster hash values for multiple clusters in the first and second dataset. For each of the composite cluster hash values, comparing a composite cluster hash value of a particular cluster in the first dataset with a composite cluster hash value of a corresponding cluster in the second dataset. When the composite cluster hash values of the corresponding clusters do not match, retrieving all tile hashes corresponding to all the tiles from the non-matching cluster in the first dataset, and retrieving all tile hashes corresponding to all the tiles from the non-matching cluster in the second dataset. Finally, determining the one or more changed tiles between the non-matching cluster in the first dataset and the non-matching cluster in the second dataset by comparing the corresponding tile hashes.
