Hi Eric Poon,
ShardingSphere requires users to configure which tables need to be shard currently. If there are no sharding-rule for sharding tables, ShardingSphere will use default-datasource to execute it. So it should not work with dynamic table names for now. -- Yi Yang(Sion) Apache ShardingSphere At 2019-07-20 05:21:10, "Eric" <etmpoon...@gmail.com> wrote: >Hi, > >I am trying to apply sharding on all tables on the same key column exists >on all tables.
