INSERT INTO test.t_order (order_id, user_id, status, t_json) VALUES (1, 2,
'1', null);
```
When execute `MIGRATE TABLE ds_0.test.t_order INTO sharding_db.t_order;`,
wait the job status is `EXECUTE_INVENTORY_TASK`.
Then execute sql `UPDATE test.t_order SET t_json = '{"test": "ok2"}' WHERE
order_id = 1;` at source datatase
