Description
Some read/write operations may yield unexpected results, for example
- reading CSV file with non-default delimiter could produce a dataframe with one column instead of 5. There is a %trackExecutions that prints generated schema, but it's either prints after each cell, or doesn't print at all
- dataframe saves nested objects with just "toString", so you couldn't read it back. Might be helpful to print paths to all columns with non-serializable objects
- ...?
One of the possible solutions is some sort of logging:

I think we need more specific use cases
