The replica nodes communicate with a coordinator node over a computer network. The method includes the steps of: (a) receiving an operation at the coordinator node; (b) transmitting the operation to the replica nodes to be executed by each replica node to generate an operation result and a hash representation of the operation or of the operation result; (c) receiving the operation result and the hash representation generated by each of the replica nodes; and (d) determining whether the operation resulted in data divergence or inconsistency by detecting when the hash representations received from the replica nodes are not all the same."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for detecting data divergence and inconsistency across replicas of data within a shared-nothing distributed database","description":"Methods and systems are disclosed for detecting data divergence or inconsistency across replicas of data maintained in replica nodes in a shared-nothing distributed computer database system.
