The Open Data Lakehouse: Why Enterprises Are Walking Away from Vendor-Locked Architectures

The article explains how vendor lock-in persists in lakehouses despite open-source components, arguing genuine openness requires portability across storage (Parquet), tables (Apache Iceberg), and catalogs (engine-agnostic solutions like Gravitino). It advocates a decoupled architecture using Iceberg, Parquet, Gravitino, Ranger, and Kubernetes-native compute to avoid costly migrations from proprietary catalog dependencies.
