Accelerate data lake operations with Apache Iceberg V3 deletion vectors and row lineage

In this post, we walk you through the new capabilities in Iceberg V3, explain how deletion vectors and row lineage address these challenges, explore real-world use cases across industries, and provide practical guidance on implementing Iceberg V3 features across AWS analytics, catalog, and storage services.

Orchestrating data processing tasks with a serverless visual workflow in Amazon SageMaker Unified Studio

In this post, we show how to use the new visual workflow experience in SageMaker Unified Studio IAM-based domains to orchestrate an end-to-end machine learning workflow. The workflow ingests weather data, applies transformations, and generates predictions—all through a single, intuitive interface, without writing any orchestration code.

Cross-account lakehouse governance with Amazon S3 Tables and SageMaker Catalog

In this post, we walk you through a practical solution for secure, efficient cross-account data sharing and analysis. You’ll learn how to set up cross-account access to S3 Tables using federated catalogs in Amazon SageMaker, perform unified queries across accounts with Amazon Athena in Amazon SageMaker Unified Studio, and implement fine-grained access controls at the column level using AWS Lake Formation.

Introducing Amazon MWAA Serverless

Today, AWS announced Amazon Managed Workflows for Apache Airflow (MWAA) Serverless. This is a new deployment option for MWAA that eliminates the operational overhead of managing Apache Airflow environments while optimizing costs through serverless scaling. In this post, we demonstrate how to use MWAA Serverless to build and deploy scalable workflow automation solutions.

Analyzing Amazon EC2 Spot instance interruptions by using event-driven architecture

In this post, you’ll learn how to build this comprehensive monitoring solution step-by-step. You’ll gain practical experience designing an event-driven pipeline, implementing data processing workflows, and creating insightful dashboards that help you track interruption trends, optimize ASG configurations, and improve the resilience of your Spot Instance workloads.

Enhanced search with match highlights and explanations in Amazon SageMaker

Amazon SageMaker now enhances search results in Amazon SageMaker Unified Studio with additional context that improves transparency and interpretability. The capability introduces inline highlighting for matched terms and an explanation panel that details where and how each match occurred across metadata fields such as name, description, glossary, and schema. In this post, we demonstrate how to use enhanced search in Amazon SageMaker.

Use trusted identity propagation for Apache Spark interactive sessions in Amazon SageMaker Unified Studio

In this post, we provide step-by-step instructions to set up Amazon EMR on EC2, EMR Serverless, and AWS Glue within SageMaker Unified Studio, enabled with trusted identity propagation. We use the setup to illustrate how different IAM Identity Center users can run their Spark sessions, using each compute setup, within the same project in SageMaker Unified Studio. We show how each user will see only tables or part of tables that they’re granted access to in Lake Formation.
