Dremio leverages Apache Iceberg’s core components to enable efficient, scalable data lakehouse management. The Storage Layer provides cost-effective, large-scale data storage using object storage and Parquet files. The Metadata Layer handles schemas, partitions, snapshots, and supports schema evolution and query optimization through detailed metadata files. The Catalog Layer ensures consistent metadata management across engines with ACID compliance. Integrated with high-performance query engines, including Dremio itself, these layers transform data lakes into reliable, flexible, high-performing lakehouses for accelerated analytics.
