Performing data validation
Now that you've defined the schema, it's time to perform data validation. In this exercise, you'll create validation rules to ensure data quality and check for common issues like duplicates and null values.
The table_schema from the previous exercise is preloaded for you, along with the ts DataFrame and pointblank library.
