### Search before asking - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar. ### Motivation I am using Flink CDC to capture changes from a MySQL database and write into a Paimon table. I'm facing an issue related to length validation for `char` and `varchar` types. When the fields contain special characters or garbled characters, Paimon's field validation fails due to mismatched lengths. The system interprets this as a schema change and keeps waiting for an updated schema to be passed in, blocking the process indefinitely. This can cause significant problems when dealing with real-world data that often includes special or unexpected characters. I'm wondering if there's a way to either disable this validation, or make it optional specifically for these field types (`char`, `varchar`). This would improve the flexibility and robustness of the CDC integration with Paimon. Thanks for considering this issue. ### Solution The system should either ignore length mismatches for `char` and `varchar` types, or provide an option to disable this validation. ### Anything else? _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.
