### 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 Document Introduction,format [String], the format of upstream data, now only support json text, default json. But in fact, it only supports json and json array, and does not support text format for example: [{},{},{}] or {} ### Usage Scenario When the data volume is large and there are many fields, it is necessary to save traffic and cannot follow the JSON format. The k value will occupy a large amount of traffic, and we hope to support the return value of file types. For example, file content: 1#xiao1#25 1#xiao2#26 1#xiao2#27 ### Related issues Yes, currently there is a portion of the data going through HTTP and there are many fields. ### 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.
