The Cosmos project has introduced native support for source node rendering, which allows for improved freshness checks and reduced wasted compute. This feature enables users to render sources natively, checking their health and adherence to SLAs before running models. It also introduces new variables, modes, and a rendered template field to provide detailed information about the freshness checks. The feature is now available in Cosmos version 1.6 or higher and can be enabled with the `ALL` or `WITH_TESTS_OR_FRESHNESS` option. This improvement aims to make dbt and Airflow workflows more efficient, tailored to real-world use cases, and better align with business priorities.
