Apache Parquet is an open source, column-oriented data file format designed for efficient data storage and retrieval.

It provides:

  • High-performance compression
  • Efficient encoding schemes
  • Support for complex data types
  • Broad adoption across analytics tools and programming languages

Parquet is commonly used as a table replacement for analytical workloads.

How to Create Parquet Files

There are several ways to create Parquet files:

  • From CSV files
  • Directly from PostgreSQL using the pg_parquet extension
  • Using DuckDB
  • Using web-based CSV to Parquet converters

In this post, DuckDB is used as a lightweight and practical tool to generate and query Parquet files.
