The problem is often not insufficient compute—it is unmanaged metadata, excessive small files, inefficient partitioning, and costly maintenance operations. This article explores how Apache Iceberg, Delta Lake, and other lakehouse technologies handle metadata, why conventional optimization strategies may fall short, and how workload-aware maintenance can improve performance and cost efficiency. The key takeaway: scaling storage is easy; scaling metadata management requires deliberate architectural decisions.","thumbnail_url":"https://img.transistorcdn.com/8VxAgS1Ll3FJEERcAdhFdqqXJMnE7OfD2RUvrjauLt0/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjY4LzE2ODM1/ODI1ODUtYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
