What is Apache Polaris?

Apache Polaris is an open-source Iceberg REST catalog that vends temporary, scoped credentials for secure table access without sharing long-lived keys.

How does Apache Polaris secure data access?

It authenticates principals, checks RBAC roles, then mints 15-minute cloud creds (AWS STS, GCP JWTs, Azure tokens) locked to specific tables and operations.

Is Apache Polaris ready for production?

Yes—used at Netflix and Cloudera for multi-tenant data platforms, with full audit trails, revocation, and multi-cloud support.
