### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Fluss version 0.8.0 (latest release) ### Please describe the bug 🐞 When creating an Iceberg table with multiple primary keys, insert or upsert operations fail with the error message: “Key fields must have exactly one field for Iceberg format, but got …”. This error is triggered by the validation logic in `IcebergKeyEncoder.` However, this constraint is only detected at runtime during insert/upsert. From a usability and correctness perspective, the same validation should be performed earlier ### Solution _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
