A method for determining common table definitions in distributed databases where a node in the distributed database independently establishes a common network definition for shared logical table names, establishing a common network definition includes: providing local definitions for one or more logical tables; querying one or more nodes in a network to determine any existing network definitions for the one or more logical tables. If there is no existing network definition, the method includes adding local definition as new network definition. If there is an existing network definition, the method comprises: updating the existing network definition with any extra columns of local definition; and pushing updated network definition to other nodes in network holding a record of that network definition. |
