Apache Polaris, the open source catalog for Apache Iceberg co-created by Dremio, has graduated to a top-level Apache Project, marking a defining milestone for open data lakehouse architectures. Now considered a self-governing, open-source software project that is managed by the Apache Software Foundation, Apache Polaris provides a community-driven, vendor-neutral catalog that enables multi-engine interoperability and eliminates lock-in to proprietary alternatives.
Why it matters
The graduation of Apache Polaris to a top-level Apache Project validates the strength of its contributor community, its adherence to the Apache Way, and its production-ready maturity. With broad adoption already underway, Polaris is positioned as the industry's de facto catalog standard for Apache Iceberg, providing an open alternative to proprietary catalogs like AWS Glue and Unity Catalog.
The details
Since its initial creation, Polaris has attracted a growing base of contributors and users. Dremio remains one of the project's most active participants, helping shape its REST catalog APIs, security model, and enterprise-grade capabilities. As an open-source, fully-featured catalog for Apache Iceberg, Apache Polaris implements Iceberg's REST API, enabling seamless multi-engine interoperability across a wide range of platforms.
