   @Glowdable Thank you for your feedback. Using default database configuration requires users to be aware of the underlying database, which requires a certain usage cost. ShardingSphere hopes that users can use it like a native database.
   
   For what you said, ShardingSphere only needs to load the sharding table, which is obviously wrong. In different scenarios, we also need the metadata of table to make decisions, such as encrypt rewriting or query optimization.
   
   Finally, if you encounter some performance issues with SingleTableRule, feedback is welcome and we will try to optimize it.
