Capacity Management and Amazon EMR Managed Scaling improvements for Amazon EMR on EC2 clusters
In 2022, we told you about the new enhancements we made in Amazon EMR Managed Scaling, which helped improve cluster utilization as well as reduced cluster costs. In 2023, we are happy to report that the Amazon EMR team has been hard at work. We worked backward from customer requirements and launched multiple new features to enhance your Amazon EMR on EC2 clusters capacity management and scaling experience. Let’s dive deeper and discuss the new Amazon EMR on EC2 features in detail.
Extracting key insights from Amazon S3 access logs with AWS Glue for Ray
This blog post presents an architecture solution that allows customers to extract key insights from Amazon S3 access logs at scale. We will partition and format the server access logs with Amazon Web Services (AWS) Glue, a serverless data integration service, to generate a catalog for access logs and create dashboards for insights.
Build streaming data pipelines with Amazon MSK Serverless and IAM authentication
Amazon’s serverless Apache Kafka offering, Amazon Managed Streaming for Apache Kafka (Amazon MSK) Serverless, is attracting a lot of interest. It’s appreciated for its user-friendly approach, ability to scale automatically, and cost-saving benefits over other Kafka solutions. However, a hurdle encountered by many users is the requirement of MSK Serverless to use AWS Identity and Access Management (IAM) access control. At the time of writing, the Amazon MSK library for IAM is exclusive to Kafka libraries in Java, creating a challenge for users of other programming languages. In this post, we aim to address this issue and present how you can use Amazon API Gateway and AWS Lambda to navigate around this obstacle.
Use the reverse token filter to enable suffix matching queries in OpenSearch
In this post, we show how you can implement a suffix-based search. OpenSearch is an open-source RESTful search engine built on top of the Apache Lucene library. OpenSearch full-text search is fast, can give the result of complex queries within a fraction of a second. With OpenSearch, you can convert unstructured text into structured text using different text analyzers, tokenizers, and filters to improve search. OpenSearch uses a default analyzer, called the standard analyzer, which works well for most use cases out of the box. But for some use cases, it may not work best, and you need to use a specific analyzer.
Stored procedure enhancements in Amazon Redshift
In this post, we discuss the enhancements to Amazon Redshift stored procedures for non-atomic transaction mode. This mode provides enhanced transaction controls that enable you to automatically commit the statements inside the stored procedure.
Optimizing Amazon OpenSearch Service performance: Fine-tuning shard size with Amazon CloudWatch storage and shard skew health
In this post, we explore how to deploy Amazon CloudWatch metrics using an AWS CloudFormation template to monitor an OpenSearch Service domain’s storage and shard skew, as well as shard sizes. This solution uses an AWS Lambda function to extract storage and shard distribution metadata from your OpenSearch Service domain, calculates the level of skew and shard sizes, and then pushes this information to CloudWatch metrics so that you can easily monitor, alert, and respond. This information will help you to meet the recommended settings for read and write throughput, performance, and fault tolerance.
Derive operational insights from application logs using Automated Data Analytics on AWS
Automated Data Analytics (ADA) on AWS is an AWS solution that enables you to derive meaningful insights from data in a matter of minutes through a simple and intuitive user interface. ADA offers an AWS-native data analytics platform that is ready to use out of the box by data analysts for a variety of use […]
Configure SAML federation for Amazon OpenSearch Serverless with Okta
Modern applications apply security controls across many systems and their subsystems. Keeping all of these systems in sync would be a major undertaking if you tried to implement it separately. Centralized identity management is the way to maintain a single identity provider (IdP) that can authenticate actors and manage and distribute their rights. OpenSearch is […]
Perform time series forecasting using Amazon Redshift ML and Amazon Forecast
Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. Tens of thousands of customers use Amazon Redshift to process exabytes of data every day to power their analytics workloads. Many businesses use different software tools to analyze historical data and past patterns to forecast future demand and trends to make more […]
Configure cross-Region table access with the AWS Glue Catalog and AWS Lake Formation
Today’s modern data lakes span multiple accounts, AWS Regions, and lines of business in organizations. Companies also have employees and do business across multiple geographic regions and even around the world. It’s important that their data solution gives them the ability to share and access data securely and safely across Regions. The AWS Glue Data […]
