This article explains how Amazon Redshift now automatically mounts the AWS Glue Data Catalog, eliminating the need to create external schemas to query data lake tables.

• Redshift automatically mounts Glue Data Catalog as "awsdatacatalog" database without manual schema creation
• Supports multiple authentication methods: IAM Identity Center, IAM credentials, federated users, and IAM roles
• Works with Redshift RA3, Redshift Serverless, and all AWS commercial and US Gov Cloud regions
• Enables querying Apache Hudi, Delta Lake, and Apache Iceberg table formats directly from Redshift
• Two implementation scenarios: IAM Identity Center authentication and non-IDC methods
• Integrates with AWS Lake Formation for fine-grained access control and data governance
• Supports Query Editor v2 and third-party SQL clients for data discovery and querying
• Uses three-part notation to reference tables: awsdatacatalog.glue_database.glue_table

This feature simplifies data lake access for analysts by automating catalog mounting while maintaining security through Lake Formation permissions and IAM policies.
