Abstract

Techniques of dynamic hash function composition for change detection in distributed storage systems are disclosed herein. In one embodiment, a method includes dynamically selecting a hash function for a property of a new version of the document and generating a hash value of the value of the property using the selected hash function. The method can then include determining whether the generated hash value of the property of the received new version is different than that of a previous version of the document in the distributed storage system. In response to determining that the generated hash value is different than that of the previous version of the document, a notification can be transmitted to one or more computing services previously registered to receive a notification regarding a change in the property without transmitting the notification to other computing services not registered to receive the notification.
