Getting started with Apache Iceberg write support in Amazon Redshift – Part 3
Amazon Redshift now supports evolving Apache Iceberg table schemas and partition layouts through ALTER statements, with no data rewrites or pipeline rebuilds. In this final post of the series, you rename, add, drop, and widen columns, evolve partitions, and create AWS Lake Formation resource links for governed cross-engine access to Amazon S3 Tables.
Enforce IAM permissions boundaries for Amazon SageMaker Unified Studio Tooling blueprints
Amazon SageMaker Unified Studio now supports custom permissions boundaries for the IAM roles its Tooling blueprint creates. Learn how to create a permissions boundary that restricts AI agent capabilities, configure it on the Tooling blueprint with the AWS CLI, and validate that every provisioned role carries the boundary.
Configure domain-level VPC networking in Amazon SageMaker Unified Studio
Configuring VPC networking per project across a SageMaker Unified Studio domain creates inconsistent, hard-to-audit networks. This post shows administrators how to configure domain-level VPC networking once, so every new project automatically inherits consistent, private network isolation, then update existing projects and validate connectivity.
Announcing Spark Connect on Amazon EMR on EC2: Interactive PySpark anywhere
Amazon EMR on EC2 now supports Spark Connect, so you can develop and debug PySpark interactively from Amazon SageMaker Unified Studio Data Notebooks or your own IDE while Spark runs on your cluster. This post shows you how to get started from both a Data Notebook and a local IDE.
Query unstructured data in Amazon SageMaker Catalog using generative AI
In Part 2 of this series, sign in as a data consumer, subscribe to enriched unstructured data assets in Amazon SageMaker Catalog, and query them using natural language through a no-code Amazon Bedrock chat agent and Amazon Bedrock model inference.
How United Airlines uses Amazon Redshift and AWS Glue Data Catalog federation to query Databricks-managed data
Learn how United Airlines uses AWS Glue Data Catalog federation to query Databricks Unity Catalog data directly from Amazon Redshift Serverless without duplicating data, using resource links and AWS Lake Formation for governance.
