Description

Some read/write operations may yield unexpected results, for example

  1. 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
  2. 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
  3. ...?

One of the possible solutions is some sort of logging:

I think we need more specific use cases

Start with the CSV delimiter and nested-object examples in the issue, then review the linked discussion in issue #138 and the %trackExecutions entry point. Done means agreeing on specific use cases and a logging or feedback behavior for generated schemas and non-serializable columns.
