# pages skipped is a good counter to add even if it doesn't give complete 
picture of saving provided. I have added it. Regarding the testing for 
different data types, code added is independent of any scalar data type so 
testing that combination is not needed. I have added end-to-end tests for other 
combinations (test_parquet_late_materialization.py).
