Overview
Apache Parquet is an open-source, columnar storage file format designed for efficient big-data processing (e.g., with Hadoop, Spark, and other analytics engines). It uses columnar storage, compression, and a rich schema to enable fast queries and reduced I/O. In cybersecurity terms, Parquet-based data stores and pipelines can become targets for misconfigurations, data leakage from unsecured access, and rapid exfiltration across analytics workloads if not properly secured.
