### Search before asking - [X] I had searched in the [feature](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description In some connector(e.g. TDengine), there are some meta info should be transferred from `source` to `sink` (e.g. sub-table-name/ tags) which are different from each data. Nevertheless, there is still no native and generic solution for this in Seatunnel. Some alternatives here to be considered: - [ ] org.apache.seatunnel.api.table.catalog.Column.MetadataColumn - [ ] org.apache.seatunnel.api.table.connector.SupportReadingMetadata ### Usage Scenario In TDengine Source: source data doesn't have tags and sub-table-name which are important to TDengine Sink to write data. ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] 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.
