Editing the Dataset Type

When you edit a dataset, you can change the underlying table or query that it points to. This allows you to iterate and develop against a smaller test dataset, then switch to the full dataset when you are ready to deploy the project.

To use this functionality, you must either:

  • Use a table that has the same schema, column names, column order, etc. as the original table.
  • Use a query dataset that is limit query on the original table.

  4. (Optional) Click Preview SQL to see the rows that the query returns.
