Thirty-two new or updated datasets from the Massachusetts Institute of Technology, the First Street Foundation, Ookla, and others are available on the Registry of Open Data in the following categories. 

Amazon CloudWatch Lambda Insights, now available in preview, enables you to monitor, troubleshoot, and optimize the performance of AWS Lambda functions. With this preview, you have access to automated dashboards summarizing the performance and health of your Lambda functions that provide visibility into issues such as memory leaks or performance changes caused by new function versions.

Amazon ElastiCache is announcing the launch of ElastiCache for Redis and Memcached on Graviton2 M6g and R6g instance families. Customers choose Amazon ElastiCache for workloads that require ultra-low latency and high throughput, and can now enjoy up to a 45% price/performance improvement over previous generation instances. Graviton2 instances are now the default choice for ElastiCache customers.  

Starting today, you can create multilevel hierarchies with AWS Cost Categories to group your cost and usage information based on your business needs. Cost Category is added as a new dimension, in addition to Tag, Account, Service, and Charge Type. Furthermore, you can now track whether your most recent cost category updates have been applied to your cost and usage data via a new “status” attribute on your Cost Categories dashboard. 

Customers can now assess their EC2 workloads running Red Hat Enterprise Linux (RHEL) 8, Ubuntu 20.04 LTS, Debian 10, and Windows Server 2019 for CVEs and external network accessibility using Inspector. Amazon Inspector is available in the following 14 regions: US East (Northern Virginia), US East (Ohio), US West (Northern California), US West (Oregon), EU (Frankfurt), EU (Ireland), EU (London), EU (Stockholm), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Sydney), Asia Pacific (Tokyo), AWS GovCloud (US-West), and AWS GovCloud (US-East).  

Amazon Kinesis Data Analytics now allows you to Force Stop a running application and reset its status to Ready, giving you more control over your applications. In addition, you can check if your application is scaling up or down through the new ‘Autoscaling’ application status.

Streaming extract, transform, and load (ETL) jobs in AWS Glue can now automatically detect the schema of incoming records and gracefully handle schema changes on a per-record basis. Previously, you needed to specify the schema of incoming data using the AWS Glue Data Catalog and update ETL scripts to handle schema changes. The AWS Glue job can now do both for you, saving time on reworking code and increasing the flexibility of your ETL jobs.

Amazon EMR now supports a spread placement group strategy for clusters with multiple master nodes. You can now launch master nodes across separate underlying hardware to reduce the risk of simultaneous failures that might occur when instances share the same racks. Earlier, master nodes were placed within the same subnet without any placement strategies. 

AWS Lake Formation now supports cross account database sharing. You can now create cross account data lakes to access data across your organization and eliminate data silos.

Amazon EventBridge now supports Dead Letter Queues (DLQs), which make event-driven applications more resilient and durable by storing your events in queues when the events can’t be delivered, or the target is unavailable.
