In 2025, Amazon Redshift delivered several performance optimizations that improved query performance over twofold for Iceberg workloads on Amazon Redshift Serverless, delivering exceptional performance and cost-effectiveness for your data lake workloads. In this post, we describe some of the optimizations that led to these performance gains.

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.

This post highlights how Octus migrated its Elasticsearch workloads running on Elastic Cloud to Amazon OpenSearch Service. The journey traces Octus’s shift from managing multiple systems to adopting a cost-efficient solution powered by OpenSearch Service.

This blog will guide you through setting up and using Cluster Insights, including key features and metrics. By the conclusion, you’ll understand how to use Cluster insights to recognize and address performance and resiliency issues within your OpenSearch Service clusters.

Amazon SageMaker Catalog now supports metadata enforcement rules for glossary terms classification (tagging) at the asset level. With this capability, administrators can require that assets include specific business terms or classifications. Data producers must apply required glossary terms or classifications before an asset can be published. In this post, we show how to enforce business glossary classification rules in SageMaker Catalog.
