I have a CSV dataset with a schema. I want to extend this dataset. So I want to create new dataset with the same columns. How can I do that ? How can I export the schema of the initial dataset ?
Thanks for your responses.

,One way you can do this is by creating a managed dataset (+Dataset > Internal > Managed Dataset) as your target dataset and utilizing the Python APIs in a notebook to get the source dataset's schema/set the target dataset's schema. Please see our documentation on get_schema and set_schema.
I've provided sample code below.
import dataiku client = dataiku.api_client() project = client.get_project("projectKey") #get the source dataset schema source_dataset = project.get_dataset("source_dataset_name") source_schema = dataset.get_schema() #set the target dataset schema target_dataset = project.get_dataset("target_dataset_name") target_schema = target_dataset.set_schema(source_schema)Please let us know if you have any questions.
Thanks!
