Amazon SageMaker Unified Studio now supports two new connection capabilities: (1) Iceberg REST Catalog (IRC) connections for external Apache Iceberg catalogs, and (2) IAM authentication for Amazon DocumentDB. Together, they let data teams connect to a broader set of governed data sources and use credential-less authentication across projects. Iceberg REST Catalog connections. SageMaker Unified Studio now supports Iceberg REST Catalog (IRC) connections, letting customers connect to external Apache Iceberg catalogs that follow the Iceberg REST specification. Supported catalog types include Snowflake Open Catalog (Polaris), Databricks Unity Catalog, and a Generic IRC type for any other spec-compliant catalog. Once connected, customers can browse the catalog in Data Explorer (list catalog/schema/table, view columns, sample data), read and write it in Visual ETL as a source or append/overwrite sink, and query it from data notebooks. Authentication uses OAuth2 or bearer token, and data access uses vended, short-lived Amazon S3 credentials. The connection lifecycle is fully supported - create, edit, delete, and test connection. IAM authentication for Amazon DocumentDB. SageMaker Unified Studio now supports IAM authentication for Amazon DocumentDB connections, so customers can connect to DocumentDB without storing a database username or password in the connection or notebook. The connection authenticates using its own IAM role, which DocumentDB validates via AWS Security Token Service (AWS STS). This requires Amazon DocumentDB 5.0 or later instance-based clusters with TLS enabled. The connection can be used from data notebooks, Data Explorer, Test Connection, and Visual ETL data preview. These connection capabilities are available today in all AWS Regions where Amazon SageMaker Unified Studio is available, at no additional cost. To learn more about Amazon SageMaker Unified Studio, refer to the Amazon SageMaker Unified Studio User Guide.

For developers building MongoDB-compatible applications, retryable writes improve application resilience during transient errors such as network interruptions or primary failovers. Amazon DocumentDB (with MongoDB compatibility) now supports retryable writes starting with engine version 8.0.2, eliminating the need for additional code changes when enabling this capability. With retryable writes, the MongoDB driver automatically retries certain write operations one time if a transient error occurs. Most current MongoDB-compatible drivers enable retryable writes by default. With this release, applications connecting to Amazon DocumentDB 8.0.2 no longer need to set retryWrites=false in the connection string to avoid errors. Retryable writes are supported for all write commands except updateMany and deleteMany, as well as transaction commit and abort commands. On engine versions earlier than 8.0.2, retryable writes remain unsupported and must be disabled. Retryable writes are available on Amazon DocumentDB 8.0.2 instance-based and serverless clusters in all regions where Amazon DocumentDB 8.0 is available. To get started with retryable writes, see the Amazon DocumentDB developer guide.
