### What would you like to be improved? ### Background MySQL supports multiple text types, including `TEXT`, `TINYTEXT`, `MEDIUMTEXT`, and `LONGTEXT`, each with different maximum length limits: - `TINYTEXT`: Maximum 255 bytes - `TEXT`: Maximum 65,535 bytes (64 KB) - `MEDIUMTEXT`: Maximum 16,777,215 bytes (16 MB) - `LONGTEXT`: Maximum 4,294,967,295 bytes (4 GB) Currently, Gravitino's MySQL type converter (`MysqlTypeConverter`) only supports the `TEXT` type, but not `TINYTEXT`, `MEDIUMTEXT`, and `LONGTEXT`. When reading table schemas from MySQL databases that contain these types, they are recognized as `ExternalType` instead of the standard `StringType`, which may cause type compatibility issues. ### How should we improve? `TINYTEXT`, `MEDIUMTEXT`, and `LONGTEXT` should be mapped to Gravitino's `StringType` just like `TEXT`, since they are essentially variable-length string types with different storage capacities. -- This is an automated message from the Apache Git Service.
