resolves dbt-labs/dbt-core#6911
Problem
dbt run
will issue a manual refresh of a materialized view if there are no changes detected during a run. This happens regardless of whether the materialized view is setup to be automatically refreshed. If the materialized view is already scheduled to be refreshed, there is no need to insert an additional refresh. This will add cost and potentially introduce unexpected data as the refresh schedule will not match what's set with the extra refresh.Solution
dbt will inspect the materialized view to determine if it is set to automatically refresh. If it is, and there are no changes, then
dbt run
will do nothing. If it is not set to automatically refresh, thendbt run
will issue a refresh command.Checklist
