Granular change detection in distributed storage systems

Abstract:

Techniques of granular change detection in distributed storage system are disclosed herein. In one embodiment, a method includes receiving a subset of data representing a new version of a document with multiple properties. The subset of data includes hash values corresponding to the properties of the document. The method further includes for each of the properties, performing a comparison of the hash values in the new version to that of the properties in a previous version of the document. Based on the performed comparison, whether the property has changed in the new version of the document is determined. The method can then include, transmitting a notification to one or more computing services previously registered to receive a notification regarding a change in the identified one of the properties without transmitting the notification to other computing services not registered to receive the notification.
