Parquet vs CSV Storage

Problem

You are setting up a data pipeline storage folder. Your manager asks why you are exporting files as .parquet instead of .csv. Write a query that outputs reason with the value: "Parquet is a columnar binary file format that supports schema validation, high compression, and efficient query execution compared to plain CSV."

Database Schema

This problem acts as a scratchpad. You will write your own DDL/DML or conceptual queries, so there is no predefined schema.
