Polaris Catalog
An interoperable, open source catalog for Apache Iceberg™
Cross-engine read and write interoperability
Take advantage of open standards to read and write from any REST-compatible engine.
Centralized access across engines
Manage Iceberg tables for all users and engines in one place.
Vendor-agnostic flexibility
Run Polaris Catalog in your infrastructure of choice — in Snowflake or your own with containers.
Maintain one data copy that many engines can query and write to
Iceberg’s open source REST protocol provides an open standard allowing you to read and write from any REST-compatible engine — Apache Flink™, Apache Spark™, PyIceberg, Trino and more.
Streamline data management with centralized access
Centralize management in Polaris Catalog, where every user and engine can find and access Iceberg tables from one place.
Run anywhere without lock-in
An open source, vendor-neutral catalog enhances interoperability with Iceberg. Soon in public preview, get started with Polaris Catalog hosted on Snowflake’s AI Data Cloud infrastructure in minutes, or self-host in your own infrastructure — either way, no lock-in. Should you want to swap your underlying infrastructure, you retain all Polaris Catalog namespaces, table definitions, and more.
