What is Great Expectations?
Great Expectations: An open-source Python framework for declaring data quality checks, called expectations, running them against datasets and producing readable reports. Teams embed it in pipelines to catch problems before data is consumed.
Great Expectations: an example
An expectation states that the column order_id must never be null and must be unique; the pipeline fails if a new batch violates it.
