Scale analytics with Amazon Redshift multi-warehouse enhancements
In this post, we introduce new capabilities of Amazon Redshift that enhance our multi-warehouse and scaling capabilities: remote materialized view (MV) operations, remote table DDL support, and concurrency scaling enhancements for zero-ETL and S3 event integration. These features help you build more scalable, performant decentralized analytics architectures on Amazon Redshift.
Amazon Redshift delivers faster performance for BI dashboards and real-time analytics
Today, we’re excited to announce a new performance optimization in Amazon Redshift that improves the response times of low-latency SQL queries, such as those used in real-time analytics applications or generated by BI dashboards. With this enhancement, you can experience improved query latencies because of a reduction in the time Amazon Redshift spends preparing SQL queries for execution. SQL queries start faster, so they return results quicker.
Optimize your Tableau integration with Amazon Redshift Serverless
In this post, we provide a guide to help you use Tableau’s Relationships and Amazon Redshift Serverless architecture to deliver sub-second insights while maximizing every Redshift Processing Unit (RPU). We also provide guidance on five key areas: data model architecture for optimal query performance, security configuration and access control, performance optimization through smart configuration, cost management strategies, and query and join optimization techniques.
Implement multi-tenant search with Amazon OpenSearch Serverless next generation
In this post, we show how the next-generation OpenSearch Serverless architecture makes the collection-per-tenant model practical for multi-tenant search.
Multi-Region identity-based access to Amazon Redshift and S3 Tables
In Part 1 of this series, we showed how to simplify enterprise data access using the Amazon Redshift integration with Amazon S3 Access Grants. In this post, we extend that solution across AWS Regions. We introduce a fictional company, AnyCompany Global, to illustrate how organizations with global operations can use AWS IAM Identity Center Multi-Region to set up consistent, identity-based access to Amazon Redshift and Amazon S3 Tables across Regions.
Autonomous troubleshooting for Medallion Architecture with AWS DevOps Agent and Apache Spark Troubleshooting Agent
In this post, we show you how to diagnose multi-layer Medallion Architecture pipeline failures in minutes using AWS DevOps Agent with Apache Spark Troubleshooting Agent integrated as an MCP server.
Why tombola chose Graviton-powered RG instances for Amazon Redshift
In this post, you learn how tombola followed a strict engineering principle: no changes to production without evidence. That meant a head-to-head comparison of RA3 versus RG on their actual workload. You also see benchmark results on Amazon S3 Tables and the migration from RA3 to RG instances.
Detecting fraud patterns across Snowflake and AWS using SageMaker Data Agent
Amazon SageMaker Data Agent launches three new capabilities in Amazon SageMaker Unified Studio notebooks: SQL analytics on Snowflake data sources, materialized view management, and interactive charting. Practitioners can use them together to query Snowflake alongside AWS data, pre-compute and schedule repeated aggregations, and create interactive visualizations from natural language prompts in a single notebook, without writing boilerplate code or switching tools. In this post, we describe the challenges these capabilities address, introduce each one, and walk through a fraud analytics scenario that demonstrates them working together in an end-to-end investigation workflow.
Automating IT support with AI: How Nexthink uses OpenSearch Service to power self-service issue resolution
In this post, we explore how Nexthink combined Amazon OpenSearch Service vector search, Amazon Bedrock, and infrastructure as code to power the Spark agent’s retrieval layer.
Introducing Private Networking for Amazon MQ for RabbitMQ
In this post, we explain how Private Networking for Amazon MQ for RabbitMQ works and walk through the setup process. Whether you’re securing a private identity provider, federating messages between brokers, or connecting to self-hosted RabbitMQ, your broker can now reach private destinations without exposing them publicly.
