Parquet file format
Parquet is the analytics-oriented file format in the GeoIP Locations monthly release catalog.
What Parquet is
Parquet is a columnar storage format. Instead of storing complete rows one after another like CSV, Parquet organizes data by column. That makes it efficient for analytical queries that only need selected fields.
Why it is useful
Parquet is well suited for large datasets, BI pipelines, DuckDB, Spark, Python, pandas, and other data engineering tools. It supports typed columns, compression, and efficient scans.
How GeoIP Locations uses it
GeoIP Locations publishes Parquet packages for users who want to perform monthly analysis, aggregate by country, group by ASN, join to internal datasets, or build reproducible reporting pipelines.
When to choose Parquet
Choose Parquet when you need analytics, batch processing, compact storage, and reliable column types.
