Concept | Dataset schemas

See the video version of this article

When you upload a dataset or connect to a dataset, Dataiku DSS detects the columns with their names and types. While uploading a dataset, you can preview it to see the columns and types. You can find the Schema tab within the Settings tab of a dataset.

When running recipes in the Flow, DSS asks if you want to update the schema. This is because the output dataset’s schema changes as you apply changes to the columns including things like date parsing and creating new computed columns. In most cases, you will update the schema.
