Description
A Parquet file is a columnar data table: each column is stored on its own, compressed and typed, so analytics tools can read only the columns they need. It is the common exchange format of data lakes, Spark, pandas and DuckDB.
A CSV file is a comma separated values file commonly used by spreadsheet programs such as Microsoft Excel or OpenOffice Calc. It contains plain text data sets separated by commas with each new line in the CSV file representing a new database row and each database row consisting of one or more fields separated by a comma. CSV files are often opened by spreadsheet programs to be organized into cells or used for transferring data between databases.
