While using TiDB Cloud, I noticed things I don't like as a developer. For instance, it doesn't support functions and procedures, which Oracle and other databases do. This means that for table-to-table operations, like data manipulation and functionality, I need to take that data to the application side, process it manually, and then re-insert it. Oracle and other databases have functions and procedures to handle this within the database itself. This is a key feature that I, as a developer, would like to see in TiDB Cloud. We are implementing our product for a major bank in Malaysia and setting up a disaster recovery environment. The client requires the ability to replicate auto-increment sequences from the production environment to the disaster recovery environment. This is not currently possible. We had a call with TiDB, and they said this feature is not available. They advised us to handle the auto-increment indexes from the application side. This means we are doing most things from the application side, which is a challenge we face with TiDB.
