Zcompress Jun 2026

: A hardware-based compression acceleration feature on IBM zSystems that uses PCIe cards to provide high-performance compression/decompression without heavily taxing the main CPU.

Storing petabytes of Parquet or ORC files in Amazon S3 or Azure Blob Storage incurs enormous costs. Zcompress can be integrated as a custom codec in Apache Hadoop, Spark, or Presto. By reducing storage footprint by 30–40%, companies save millions annually. Furthermore, because decompression is fast (800 MB/s), query performance doesn't suffer. zcompress
