Understanding group-based ownership in dbt

In dbt, group-based ownership helps manage access and responsibilities for models. Which statement best describes the main benefit of using group-based ownership?

A It enables version control integration for group-owned models.

B It automatically generates documentation for all models owned by a group.

C It restricts model execution to only one user at a time within a group.

D It allows assigning ownership to multiple users collectively, simplifying permission management.

💡 Hint

Think about how managing permissions for many users can be easier when grouped.

Group-based ownership lets you assign ownership to a group instead of individual users, making permission management simpler and more scalable.

Output of ownership YAML configuration

Given this dbt ownership YAML snippet, what is the list of owners for the model sales_summary?

models:
  - name: sales_summary
    owners:
      - group: analytics_team
      - user: alice

A ["analytics_team", "alice"]

B ["analytics_team"]

C ["alice"]

D []

💡 Hint

Look at both group and user keys under owners.

The owners list includes both the group analytics_team and the user alice.

Result of dbt ownership query

Consider this SQL query to list owners of models with group ownership in dbt metadata:

SELECT model_name, owner
FROM ownership
WHERE owner_type = 'group';

If the ownership table contains:

| model_name    | owner           | owner_type |
|---------------|-----------------|------------|
| sales_summary | analytics_team  | group      |
| sales_summary | alice           | user       |
| user_data     | data_engineers  | group      |
| user_data     | bob             | user       |

What is the query output?

A

| sales_summary | analytics_team |
| sales_summary | alice |

B

| sales_summary | alice |
| user_data     | bob |

C

| sales_summary | analytics_team |
| user_data     | data_engineers |

D

| user_data     | data_engineers |
| user_data     | bob |

💡 Hint

Filter only rows where owner_type is 'group'.

The query selects only owners with owner_type = 'group', so only group owners appear.

Identify error in group ownership YAML

Which option shows the error in this dbt ownership YAML snippet?

models:
  - name: customer_data
    owners:
      - group: data_team
      - group: analytics_team
      - user: john

A The YAML is valid; multiple groups and users can be owners.

B Only one owner is allowed per model; multiple owners cause an error.

C Duplicate 'group' keys under owners cause a syntax error.

D The 'user' key must come before any 'group' keys.

💡 Hint

Check if YAML allows multiple entries with the same key inside a list.

The YAML is valid because owners is a list of dictionaries, each with a single key. Multiple groups and users can be owners.

Assigning group ownership with dbt permissions

You want to assign ownership of the finance_reports model to the finance_team group so that all members can edit and run it. Which YAML snippet correctly sets this group-based ownership?

A

models:
  - name: finance_reports
    owners:
      - user: finance_team

B

models:
  - name: finance_reports
    owners:
      - group: finance_team

C

models:
  - name: finance_reports
    owners:
      - group: finance_team
      - user: finance_team

D

models:
  - name: finance_reports
    owners:
      - group: finance_team
    permissions:
      - edit
      - run

💡 Hint

Ownership is assigned under owners with group key; permissions are managed separately.

Option B correctly assigns the group finance_team as owner. Permissions like edit and run are managed by dbt roles, not in ownership YAML.
