Discover the Power of Compression in Parquet Files!

Compression plays a crucial role in managing large datasets, and Parquet files are no exception. This columnar storage format offers highly effective compression, thanks to storing similar data together. But which compression algorithm should you choose? Learn about Snappy, Gzip, Brotli, Zstandard (ZSTD), and LZO, and how they impact file size, read/write performance, and CPU usage.

Consider your specific use case: prioritize query speed with Snappy or ZSTD, or focus on storage efficiency with Gzip or Brotli. Real-time processing systems might benefit from Snappy or LZO's fast decompression speeds.

Compression is just one aspect of efficient data storage. Stay tuned for our next post to learn about encoding techniques and how they complement compression in Parquet files!
