Securing client confidentiality at scale: Automated data discovery and governed analytics for legal workloads
In this post, we show you a reference architecture that automates sensitive data discovery across legal document repositories on Amazon Web Services (AWS), demonstrate how to capture structured findings as a compliance dataset, and guide you through building a governed analytics workspace that maintains your security boundaries. You walk away with a practical model for building security and analytics into the same lifecycle, without moving documents outside their system of record.
Streamlined monitoring and debugging for Amazon EMR on EC2
In this post, we walk you through five key enhancements: Amazon CloudWatch Logs integration, step-level Amazon Simple Storage Service (Amazon S3) logging controls, expanded console UIs for YARN and Tez, Amazon EMR step to YARN application ID mapping, and enhanced custom metrics with updated documentation.
Improve DynamoDB analytics with AWS Glue zero-ETL schema and partition controls
In this post, you learn how to replicate Amazon DynamoDB data to Apache Iceberg tables in Amazon S3 through a zero-ETL integration. We walk through the challenges that the DynamoDB nested, schema-flexible data model introduces for analytics workloads, and show you how to configure schema unnesting and data partitioning for a sample product catalog table. We also cover how to query the replicated data in Amazon Athena using standard SQL.
How to build a cross-Region resilience for Amazon OpenSearch Service with Amazon MSK
In this post, we outline the solution that provides cross-Region resiliency without needing to reestablish relationships during a fail-back, using an active-active replication model with Amazon OpenSearch Ingestion (OSI) and Amazon Managed Streaming for Apache Kafka (Amazon MSK). This solution applies to both OpenSearch Service managed clusters and Amazon OpenSearch Serverless collections. We use Amazon OpenSearch Serverless as an example for the configurations in this post.
How to consolidate cross-Region S3 data into OpenSearch
We’re happy to announce that Amazon OpenSearch Ingestion pipelines can now read from S3 buckets in different Regions to ingest and consolidate data into a single OpenSearch Service domain or collection. In this post, I’ll show you how to use the new cross-Region support to ingest data from S3 buckets across multiple AWS Regions into a single OpenSearch Service domain or collection.
Build streaming applications on Amazon Managed Service for Apache Flink with AI-assisted guidance
In this post, we walk through installing the Power and Skill, using Amazon Kinesis Data Streams to build a Kinesis Data Stream-to-Kinesis Data Stream streaming pipeline, and migrating an existing application to Flink 2.2. You can follow along with this use case to see how the Managed Service for Apache Flink Kiro Power can help you build a resilient, performant application grounded in best practices.
Migrate to Apache Flink 2.2 on Amazon Managed Service for Apache Flink
In this post, we explain what’s new in Amazon Managed Service for Apache Flink 2.2, provide a guided migration using CLI commands, console instructions, and code examples, and show you how to monitor the upgrade and roll back if needed.
Using Apache Sedona with AWS Glue to process billions of daily points from a geospatial dataset
In this post, we explore how to use Apache Sedona with AWS Glue to process and analyze massive geospatial datasets.
Analyzing your data catalog: Query SageMaker Catalog metadata with SQL
In this post, we demonstrate how to use the metadata export capability in Amazon SageMaker Catalog and perform analytics such as historical changes, monitor asset growth and track metadata improvements.
Configure a custom domain name for your Amazon MSK cluster enabled with IAM authentication
In the first part of Configure a custom domain name for your Amazon MSK cluster, we discussed about why custom domain names are important and provided details on how to configure a custom domain name in Amazon MSK when using SASL_SCRAM authentication. In this post, we discuss how to configure a custom domain name in Amazon MSK when using IAM authentication.
