About Nademark

We're a team of Big Data specialists with over 20 years of consulting experience. Across industries, we repeatedly saw teams land data on Amazon S3 as CSV or JSON-formats that are flexible, widely supported, and easy to inspect. But for analytics and long-term storage, converting them to Parquet consistently delivered major gains in performance, cost, and reliability through columnar compression and partitioning. To close the gap, we built a fast, reliable S3-to-Parquet solution and offer it as a product on AWS Marketplace.
