In this post, we explore how LaunchDarkly scaled the internal analytics platform up to 14,000 tasks per day, with minimal increase in costs, after migrating from another vendor-managed Apache Airflow solution to AWS, using Amazon Managed Workflows for Apache Airflow (Amazon MWAA) and Amazon Elastic Container Service (Amazon ECS).

In this post, we show how to grant Amazon S3 permissions to IAM Identity Center users and groups using S3 Access Grants. We also test the integration using an IAM Identity Center federated user to unload data from Amazon Redshift to Amazon S3 and load data from Amazon S3 to Amazon Redshift.

With SageMaker Lakehouse, you can access tables stored in Amazon Redshift managed storage (RMS) through Iceberg APIs, using the Iceberg REST catalog backed by AWS Glue Data Catalog. This post describes how to integrate data on RMS tables through Apache Spark using SageMaker Unified Studio, Amazon EMR 7.5.0 and higher, and AWS Glue 5.0.

In this blog post, we tell you how we enhanced the snapshot efficiency in Amazon OpenSearch Service while carefully maintaining these critical operational aspects. These snapshot optimizations are enabled for all OpenSearch optimized instance family (OR1, OR2, OM2) domains from version 2.17 onwards.

In this post, we introduce authorization policies for custom asset types—a new governance capability in Amazon SageMaker that gives organizations fine-grained control over who can create and manage assets using specific templates. This feature enhances data governance by allowing teams to enforce usage policies that align with business and security requirements across the organization.

In this post, we share how AppsFlyer successfully migrated their massive data infrastructure from self-managed Hadoop clusters to Amazon EMR Serverless, detailing their best practices, challenges to overcome, and lessons learned that can help guide other organizations in similar transformations.

In this post, we show you how to share an Amazon Redshift table and Amazon S3 based Iceberg table from the account that owns the data to another account that consumes the data. In the recipient account, we run a join query on the shared data lake and data warehouse tables using Spark in AWS Glue 5.0. We walk you through the complete cross-account setup and provide the Spark configuration in a Python notebook.

today we introduced Amazon Q Developer support in OpenSearch Service. With this AI-assisted analysis, both new and experienced users can navigate complex operational data without training, analyze issues, and gain insights in a fraction of the time. In this post, we share how to get started using Amazon Q Developer in OpenSearch Service and explore some of its key capabilities.

In this post, we demonstrate how PyIceberg, integrated with the AWS Glue Data Catalog and AWS Lambda, provides a lightweight approach to harness Iceberg’s powerful features through intuitive Python interfaces. We show how this integration enables teams to start working with Iceberg tables with minimal setup and infrastructure dependencies.

With OpenSearch version 2.19, Amazon OpenSearch Service now supports hardware-accelerated enhanced latency and throughput for binary vectors. In this post, we discuss the improvements these advanced processors provide to your OpenSearch workloads, and how it can help you lower your total cost of ownership (TCO).
