Learn how Apache Polaris is becoming the open catalog layer for every engine and format. Engineers from Snowflake and other organizations will walk through new capabilities including S3-compatible on-prem storage, generic tables, a built-in policy store, audit logs and events, catalog federation and the evolving Polaris REST catalog spec. A customer and a partner will demonstrate how they use and contribute to Polaris, including Delta, Lance format support beyond Iceberg and concrete ways you can get involved.

Interoperable governance means enforcing consistent row- and column-level security across all engines without fragmenting policies. How do you achieve this when engines differ? This talk presents two approaches via Apache Iceberg: Catalog-enforced FGAC using scan planning to return policy-enforced files ReadRestrictions standardization where catalogs return policy expressions engines interpreted for deeper integration You'll learn catalog-side architecture, including scan planning and policy evaluation. You'll also learn about two paths: transparent enforcement vs ReadRestrictions standardization — and trade-offs around interoperable governance.
