Oracle NoSQL Database supports Multi-Region Architecture in which you can create tables in multiple KVStores, and still maintain consistent data across these clusters. Each KVStore cluster in a Multi-Region Oracle NoSQL Database setup is called a Region. A Multi-Region Table or MR Table is a global logical table that is stored and maintained in different regions. MR Tables maintain consistent data in all the regions. That is, any updates made to an MR Table in one region automatically applies to the corresponding MR Table in all the other participating regions. To learn more about Oracle NoSQL Database Multi-Region Architecture and MR Tables, see Multi-Region Architecture in the Concepts Guide.
Note:A child MR table is not supported because of its undefined semantics.
