Determining common table definitions in distributed databases includes receiving a query at a node in a distributed database. The query targets a logical table. Upon determining the logical table is locally defined, one of the local definition and a network definition is selected to use. The network definition is independently established for shared logical table names. The selected definition is used and propagated with the query through the distributed database. Upon determining the logical table is not locally defined, an initial query is issued to other nodes in network to find the network definition for the logical table, the network definition is stored in memory, and the selected definition is propagated through the distributed database with the query. |
