Abstract:
Techniques of property grouping for change detection in distributed storage systems are disclosed herein. In one embodiment, a method includes grouping multiple properties of a document into multiple groups individually including a subset of the multiple properties. For each of the multiple groups, a hash value of the group is generated based on values of the subset of properties in the group. The method further includes determining whether the generated hash value of the group is different than that of a corresponding group in a previous version of the document in the distributed storage system. In response to determining that generated hash value of the group is not different than that of the corresponding group in the previous version, metadata is inserted into the new version of the document indicating that none of the subset of properties in the group has changed.
