   But it still may be helpful for better understanding the connection between the formal SQL and the actual SQL, since in the real application, the sharding rules can be extremely complex and cause high cardinality, right?
   
   For example, we can use OAL to calculate the metrics (Avg. Latency, Error Rate, etc.) for the formal SQL to understand the performance of SQL execution for some particular business logic. Due to fragmentations of actual SQLs, we are not able to have a general performance view at this level.
