**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) **Describe the solution you'd like** When building DAG of transformations, I want to be able define `tests` which can prove data correctness. On the end to the DAG I should be able to o review data quality and provide context to end user if required. Like in [Deequ](https://github.com/awslabs/deequ) I can check if all id's are unique or in some column I can find data in correct format. Other approaches [Apache Glue](https://docs.aws.amazon.com/glue/latest/ug/gs-data-quality-chapter.html), [dbt test](https://docs.getdbt.com/docs/build/tests) or [Great Expectation](https://github.com/great-expectations/great_expectations) **Describe alternatives you've considered** Instead of building framework it's maybe possible to extend [Great Expectation](https://github.com/great-expectations/great_expectations) **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
