menghaoranss commented on issue #4478: Is this possible to just shard databases with table rule configuration? URL: https://github.com/apache/incubator-shardingsphere/issues/4478#issuecomment-593281706 > @bharathikannan-zarget could you provide a full sharding rule configurations of your application? > And do you expect the tables in the shard databases to be exactly the same ? just like: > > ``` > db0.user (0-100) > db1.user(101-200) > ``` I suggest, you can refer to examples/sharding-jdbc-example/other-feature-example/hit-example. Use hint strategy to achieve only shard databases. The following configuration may help you: ``` shardingRule: tables: t_order: actualDataNodes: ds_${0..1}.t_order t_order_item: actualDataNodes: ds_${0..1}.t_order_item bindingTables: - t_order,t_order_item broadcastTables: - t_address defaultDatabaseStrategy: hint: algorithmClassName: org.apache.shardingsphere.example.hint.raw.jdbc.ModuloHintShardingAlgorithm defaultTableStrategy: none: ``` then you should implement yourself algorithmClass for your sharding rule of databases.
