Patent number: 11210185Abstract: The present teaching relates to request management and data recovery in a data system. In one example, a failure in connection with first data is detected at a first node in a data system. Information associated with a most recent transaction related to the first node is obtained from the persistent storage. Each of other nodes in the data system is requested to transmit one or more transaction requests previously sent to the first node after the most recent transaction. The one or more transaction requests are received from at least one of the other nodes. A sequence of one or more transactions associated with the one or more transaction requests is determined. The one or more transactions are executed according to the sequence in order to recover the first data at the first node.Type: GrantFiled: September 18, 2019Date of Patent: December 28, 2021Assignee: VERIZON MEDIA INC.Inventors: Guangxin Yang, Dongyue Wang, Sihan Ge, Xinyu Wang, Wei Liang
