   i think If you choose sub-database and sub-table, then your business volume must be very large. If the business data of a single table in the transaction database exceeds 10 million, sub-tables will be used, and you also sub-database, the transaction data should exceed 100 million At this time, if it is a query without a partition key, such an access request should be rejected from the access middleware.
   
   Once such a request is sent to the database, it may consume a lot of database resources and cause business damage.
