Zero-Copy Mirroring for Modern Lakehouse Migration

This article discusses zero-copy mirroring as a safer migration path for modern lakehouse architectures, emphasizing that teams can expose a lakehouse surface before duplicating data or rewriting workloads. It covers market signals, architecture details (source system as record, metadata translation, Iceberg-backed mirroring), validation strategies, and the separation of responsibilities among table formats, catalogs, query engines, semantic layers, and agent interfaces. The article provides implementation checklists, failure modes, and recommendations for executives and engineers, highlighting the trend toward multi-engine, agent-facing data platforms. It is highly relevant to IT/technology, focusing on data engineering, cloud architecture, and open data standards.
