Patent number: 9824132Abstract: Disclosed are a method and system for recovering a distributed system from a failure of a data storage unit. The distributed system includes a plurality of computer systems, each having a read-write computer and a data storage unit. Data is replicated from a particular data storage unit to other data storage units using publish-subscribe model. A read-write computer receives the replicated data, processes the data for any conflicts and stores it in the data storage unit. If a data storage unit fails, another data storage unit that has latest data corresponding to the failed data storage unit is determined and the latest data is replicated to other data storage units. Accordingly, the distributed system continues to have the data of the failed data storage unit. The failed data storage unit may be reconstructed using data from one of the other data storage units in the distributed system.Type: GrantFiled: January 8, 2013Date of Patent: November 21, 2017Assignee: Facebook, Inc.Inventors: Sachin Kulkarni, Sanjeev Kumar, Harry Li, Laurent Demailly, Liat Atsmon Guz
