Hi folks, Just wanted to surface a new API spec update proposal related to Catalog Federation:
https://github.com/apache/polaris/pull/1506 This adds support for AWS SigV4 authentication, enabling Polaris to federate to external Iceberg REST catalogs hosted behind services like AWS Glue, S3Tables, or API Gateway. It builds on earlier federation work and introduces a set of properties to support role assumption and request signing via SigV4. Feedback on the spec or implementation is welcome! Best, Rulin
