CREATE SHARDING TABLE REFERENCE RULE
- Sharding table reference rule can only be created for sharding tables;
- The referenced sharding tables should be sharded in the same storage units and have the same number of sharding nodes. For example
ds_${0..1}.t_order_${0..1}
andds_${0..1}.t_order_item_${0..1}
; - The referenced sharding tables should use consistent sharding algorithms. For example and
t_order_item_{order_item_id % 2}
;
