Connecting AWS Glue Data Catalog to Snowflake Horizon Catalog for Federated Analytics

Snowflake Horizon Catalog data can be accessed directly through the AWS Glue Data Catalog via catalog federation. This integration enables discovery and querying of Horizon Catalog data in Iceberg format through REST endpoints, applying fine-grained access controls using AWS Lake Formation. The new catalog federation combined with Snowflake's catalog-linked database feature allows users to access data stored across AWS and Snowflake from a single point of entry, reducing data movement and associated costs.
