Amazon SageMaker Catalog expands discoverability and governance for Amazon S3 general purpose buckets

In July 2025, Amazon SageMaker announced support for Amazon Simple Storage Service (Amazon S3) general purpose buckets and prefixes in Amazon SageMaker Catalog that delivers fine-grained access control and permissions through S3 Access Grants. In this post, we explore how this integration addresses key challenges our customers have shared with us, and how data producers, such as administrators and data engineers, can seamlessly share and govern S3 buckets and prefixes using S3 Access Grants, while making it readily discoverable for data consumers.

The Amazon SageMaker lakehouse architecture now automates optimization configuration of Apache Iceberg tables on Amazon S3

The Amazon SageMaker lakehouse architecture now automates optimization of Iceberg tables stored in Amazon S3 with catalog-level configuration, optimizing storage in your Iceberg tables and improving query performance. This post demonstrates an end-to-end flow to enable catalog level table optimization setting.

Integrate scientific data management and analytics with the next generation of Amazon SageMaker, Part 1

In this blog post, AWS introduces a solution to a common challenge in scientific research – the inefficient management of fragmented scientific data. The post demonstrates how the next generation of Amazon SageMaker, through its Unified Studio and Catalog features, helps scientists streamline their workflow by integrating data management and analytics capabilities.

Introducing MCP Server for Apache Spark History Server for AI-powered debugging and optimization

Today, we’re announcing the open source release of Spark History Server MCP, a specialized Model Context Protocol (MCP) server that transforms this workflow by enabling AI assistants to access and analyze your existing Spark History Server data through natural language interactions. This project, developed collaboratively by AWS open source and Amazon SageMaker Data Processing, turns complex debugging sessions into conversational interactions that deliver faster, more accurate insights without requiring changes to your current Spark infrastructure. You can use this MCP server with your self-managed or AWS managed Spark History Servers to analyze Spark applications running in the cloud or on-premises deployments.

Improve RabbitMQ performance on Amazon MQ with AWS Graviton3-based M7g instances

Amazon MQ is a fully managed service for open-source message brokers such as RabbitMQ and Apache ActiveMQ. Today, we are announcing the availability of AWS Graviton3-based Rabbit MQ brokers on Amazon MQ, which runs on Amazon EC2 M7g instances. AWS Graviton processors are custom designed server processors developed by AWS to provide the best price performance for cloud workloads running on Amazon EC2.

Unifying data insights with Amazon QuickSight and Amazon SageMaker

Amazon SageMaker has announced an integration with Amazon QuickSight, bringing together data in SageMaker seamlessly with QuickSight capabilities like interactive dashboards, pixel perfect reports and generative business intelligence (BI)—all in a governed and automated manner. In this post, we walk through the complete process of integrating Amazon QuickSight with Amazon SageMaker Unified Studio, demonstrating how teams can move from raw data to published dashboards in a secure and governed environment.

Compaction support for Avro and ORC file formats in Apache Iceberg tables in Amazon S3

In this post, we explore how Amazon S3 Tables has expanded its automatic compaction capabilities to include Avro and ORC file formats for Apache Iceberg tables, alongside the previously supported Parquet format. Through performance testing with over 20 billion events, the capability demonstrates significant query performance improvements ranging from 12% to 40% when using compacted tables compared to non-compacted tables across different file formats.

Orchestrate data processing jobs, querybooks, and notebooks using visual workflow experience in Amazon SageMaker

Today, we are excited to launch a new visual workflows builder in SageMaker Unified Studio. With the new visual workflow experience, you don’t need to code the Python DAGs manually. Instead, you can visually define the orchestration workflow in SageMaker Unified Studio, and the visual definition is automatically converted to a Python DAG definition that is supported in Airflow.This post demonstrates the new visual workflow experience in SageMaker Unified Studio.
