ShardingSphere also plans to cite Hint through special notation in SQL, so that users can use that function in a more transparent way. The SQL designated with sharding hint will ignore the former sharding ORDER BY user_id, order_item_id; Another situation of column derivation is using AVG aggregation function. In distributed situations, it is not right to calculate the average value with avg1 + avg2 + avg3 acquired from all the data nodes as one result set and returning it to the request end rightly. In function, the result merger supported by ShardingSphere can be divided into five kinds, iteration, order‐by

In order to achieve the core of the job more purely, the server function may be deleted in the future, and the ability to control whether the server is disabled should
