摘要： System, methods and articles of manufacture for replicating relational data on multiple nodes. An embodiment comprises receiving an update request message from a node, wherein the update request message comprises a node identification and an application identification, accessing an application schema based on the application identification, identifying a partition residing in the application schema based on the node identification, accessing a server schema, identifying a second partition residing in the server schema based on the application identification, determining at least one data change stored in the second partition that changes data associated with the first partition, retrieving at least one data change from the second partition, formatting data change in an update response message, and transmitting the update response message to the node.
