Announcing EMR Release 5.24.0: With performance improvements in Spark, new versions of Flink, Presto, and Hue, and enhanced CloudFormation support for EMR Instance Fleets

By

You can now use Apache Spark 2.4.2, Apache Flink 1.8.0, Presto 0.219, Hue 4.4.0, JupyterHub 0.9.6, Apache Livy 0.6.0, and Apache MXNet 1.4.0 on Amazon EMR release 5.24.0.

This release also includes three new performance optimizations which you can enable and improve Spark performance by up to 13X: Dynamic partition pruning, Flattening scalar subqueries, and DISTINCT before INTERSECT.

  • Dynamic partition pruning allows the Spark engine to dynamically infer relevant partitions at runtime, saving time and compute resources by both reading less data from storage, and processing less records.
  • Flatten scalar subqueries helps in situations where multiple different conditions need to be applied to rows from a specific table, and prevents the table from being read multiple times for each condition. This reduces redundant data reads and improves performance.
  • DISTINCT before INTERSECT eliminates duplicate values in each input collection prior to computing the intersection, improving performance by reducing the amount of data shuffled between hosts.

You need to enable these optimizations via Spark properties. Please refer to the EMR 5.24.0 release notes to learn more about these features.

Additionally, you can now use CloudFormation templates and specify multiple subnets for different Availability Zones within a VPC when you launch clusters using EMR Instance Fleets. This feature is available from EMR versions 4.8.0 and greater (with the exception of 5.0.x)

Amazon EMR release 5.24.0 is now available in all supported regions for Amazon EMR .

You can create an Amazon EMR cluster with the release 5.24.0 by choosing the release label “emr-5.24.0” from the AWS Management Console, AWS CLI, or SDK. You can choose Spark, Flink, Presto, Hue, JupyterHub, Livy, and MXNet to install these applications when you launch your EMR cluster. Please visit the Amazon EMR documentation for more information about EMR release 5.24.0 , Spark 2.4.2 , Flink 1.8.0 , Presto 0.219 , Hue 4.4.0 , JupyterHub 0.9.6 , Livy 0.6.0 , and MXNet 1.4.0 .

New AWS Partner Network Program, Authority to Operate on AWS

By

Security and compliance are primary considerations for many of our customers as they begin their cloud journey. Oftentimes, public sector customers face obstacles and challenges using commercially available solutions today do not meet the security and compliance authorizations needed to operate in the public sector.

Introducing the new Authority to Operate (ATO) on AWS Program to help APN Partners running on AWS accelerate the security and compliance authorization process, reducing the time and cost it takes to achieve an ATO from their customers, which is required for production use (such as FedRAMP or CJIS).

Through the ATO on AWS Program, APN Partners receive the resources needed to build, implement, and optimize DevOps, SecOps, Continuous Integration, Continuous Delivery (CI/CD), Continuous Risk Treatment (CRT) strategies and processes for their organization, as well as provide access to managed solutions that minimize the work required to achieve such authorizations.

Amazon DynamoDB on-demand and transactions now available in the AWS GovCloud (US) Regions

By

Amazon DynamoDB on-demand capacity mode and transactions are now available in the AWS GovCloud (US) Regions . On-demand capacity mode is a flexible capacity mode for DynamoDB capable of serving thousands of requests per second without requiring capacity planning. Transactions provide developers atomic, consistent, isolated, and durable (ACID) operations in DynamoDB so that they can maintain data correctness in applications more easily.
