### 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 We need to have a tool to convert data type between SeaTunnel data type and connector data type. I plan to add new method in Catalog ```java public interface Catalog { /** * Return a {@link DataTypeConvertor} used to convert the data type between SeaTunnel and the connector. */ DataTypeConvertor<?> getDataTypeConvertor(); } public interface DataTypeConvertor<T> { /** * Transfer the data type from connector to SeaTunnel. * * @param t origin data type * @param dataTypeProperties origin data type properties, e.g. precision, scale, length * @return SeaTunnel data type */ // todo: If the origin data type contains the properties, we can remove the dataTypeProperties. SeaTunnelDataType<?> from(T t, Map<String, Object> dataTypeProperties) throws DataTypeConvertException; /** * Transfer the data type from SeaTunnel to connector. * * @param seaTunnelDataType seaTunnel data type * @param dataTypeProperties seaTunnel data type properties, e.g. precision, scale, length * @return origin data type */ // todo: If the SeaTunnel data type contains the properties, we can remove the dataTypeProperties. T to(SeaTunnelDataType<?> seaTunnelDataType, Map<String, Object> dataTypeProperties) throws DataTypeConvertException; } ``` ### 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.
