The only lakehouse built natively for Apache Iceberg from the ground up ships the latest V3 spec at GA while expanding its role in the open source community.
Dremio, the Agentic Lakehouse company, today highlighted its leadership across the Apache Iceberg ecosystem, including V3 support now available in Dremio Cloud, the election of Dremio engineer JB Onofre to the Apache Software Foundation board, and continued momentum behind Apache Polaris. A longstanding advocate for open-source collaboration and the elimination of vendor lock-in, Dremio has made foundational contributions to projects including Apache Arrow (co-creator and core contributor), Apache Iceberg (contributor and leading educator), and Apache Polaris (co-creator). Reinforcing this commitment, JB Onofre, who shepherded Polaris through incubation, has been elected to the Apache Software Foundation board.
Iceberg V3 is designed to support more diverse and complex data types, offer greater control over schema evolution, and deliver performance enhancements for large-scale, high-concurrency environments. Dremio’s V3 integration advances handling of semi-structured data, row-level changes, and schema evolution, with full support in Dremio Cloud, including the VARIANT data type for JSON, deletion vectors for faster CDC (change data capture), and improved schema evolution.
