### Search before asking - [x] I had searched in the [feature](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description We have the following application scenario: In our data synchronization task, the data source is S3File. Each synchronization specifies the `path` that needs to be processed. Under this `path`, there are multiple CSV files. The formats of these CSV files are not entirely consistent, but they all contain header columns and conform to the RFC 4180 standard. For example: - The column order of CSV file 1 is as follows: `cl1, cl2, cl5, cl6, cl7`. - The column order of CSV file 2 is as follows: `cl2, cl1, cl6, cl5, cl8`. If we want to synchronize columns `cl1` and `cl2`, we need to specify `cl1` and `cl2` in the schema. However, because the column orders of the two files are different, the data will be mismatched. As a result, the two files cannot be synchronized within the same source node. We hope to incorporate the CSV's `header line` for file parsing. This would greatly facilitate data synchronization. ### Usage Scenario _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
