Configuring seeds

Seeds can only be configured from yaml files, either in dbt_project.yml or within an individual seed's yaml properties. It is not possible to configure a seed from within its CSV file.

Seed configurations, like model configurations, are applied hierarchically — configurations applied to a marketing subdirectory will take precedence over configurations applied to the entire jaffle_shop project, and configurations defined in a specific seed's properties will override configurations defined in dbt_project.yml.

Examples

Apply the schema configuration to all seeds

To apply a configuration to all seeds, including those in any installed packages, nest the configuration directly under the seeds key:

dbt_project.yml
seeds:
+schema: seed_data

Apply the schema configuration to all seeds in your project

To apply a configuration to all seeds in your project only (i.e. excluding any seeds in installed packages), provide your project name as part of the resource path.

For a project named jaffle_shop:

dbt_project.yml
seeds:
jaffle_shop:
+schema: seed_data

Similarly, you can use the name of an installed package to configure seeds in that package.

Apply the schema configuration to one seed only

To apply a configuration to one seed only, provide the full resource path (including the project name, and subdirectories).

seeds/marketing/properties.yml
version: 2
seeds:
- name: utm_parameters
config:
schema: seed_data

In older versions of dbt, you must define configurations in dbt_project.yml and include the full resource path (including the project name, and subdirectories). For a project named jaffle_shop, with a seed file at seeds/marketing/utm_parameters.csv, this would look like:

dbt_project.yml
seeds:
jaffle_shop:
marketing:
utm_parameters:
+schema: seed_data

Example seed configuration

The following is a valid seed configuration for a project with:

  • name: jaffle_shop
  • A seed file at seeds/country_codes.csv, and
  • A seed file at seeds/marketing/utm_parameters.csv
dbt_project.yml
name: jaffle_shop
...
seeds:
jaffle_shop:
+enabled: true
+schema: seed_data
# This configures seeds/country_codes.csv
country_codes:
# Override column types
+column_types:
country_code: varchar(2)
country_name: varchar(32)
marketing:
+schema: marketing # this will take precedence
