Running a subset of asset checks

Data freshness checks

Freshness checks provide a way to identify data assets that are overdue for an update. For example, you can use freshness checks to identify stale assets caused by:

Unit testing assets and ops

Unit testing is essential for ensuring that computations function as intended. In the context of data pipelines, this can be particularly challenging. However, Dagster streamlines the process by enabling direct invocation of computations with specified input values and mocked resources, making it easier to verify that data transformations behave as expected.
