Amazon Keyspaces (for Apache Cassandra) now supports Logged Batches

By

Amazon Keyspaces (for Apache Cassandra) now supports Logged Batches, enabling you to perform multiple write operations as a single atomic transaction. With Logged Batches, you can ensure that either all operations (INSERT, UPDATE, DELETE) within a batch succeed or none of them do, maintaining data consistency across multiple rows and tables within a keyspace. This capability is particularly valuable for applications that require strong data consistency, such as financial systems, inventory management, and user profile updates that span multiple data entities.

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra–compatible database service. Amazon Keyspaces is serverless, so you pay for only the resources that you use and you can build applications that serve thousands of requests per second with virtually unlimited throughput and storage.

Logged Batches in Amazon Keyspaces provide the same atomicity guarantees as Apache Cassandra while eliminating the operational complexity of managing transaction logs across distributed clusters. It’s designed to scale automatically with your workload and maintain consistent performance regardless of transaction volume. The feature integrates seamlessly with existing Cassandra Query Language (CQL) statements, allowing for adoption in both new and existing applications.

Logged Batches are available today in all AWS Commercial and AWS GovCloud (US) Regions where Amazon Keyspaces is available. You pay only for the standard write operations processed within each batch. To learn more about Logged Batches, please visit our blog post or refer to our Amazon Keyspaces documentation .

Amazon EC2 I7i instances now available in additional AWS regions

Amazon Web Services (AWS) announces the availability of high performance Storage Optimized Amazon EC2 I7i instances in the AWS Asia Pacific (Hyderabad), Canada (Central) regions. Powered by 5th generation Intel Xeon Scalable processors with an all-core turbo frequency 3.2 GHz, these new instances deliver up to 23% better compute performance and more than 10% better price performance over previous generation I4i instances. Powered by 3rd generation AWS Nitro SSDs, I7i instances offer up to 45TB of NVMe storage with up to 50% better real-time storage performance, up to 50% lower storage I/O latency, and up to 60% lower storage I/O latency variability compared to I4i instances.

I7i instances offer the best compute and storage performance for x86-based storage optimized instances in Amazon EC2, ideal for I/O intensive and latency-sensitive workloads that demand very high random IOPS performance with real-time latency to access the small to medium size datasets (multi-TBs). Additionally, torn write prevention feature support up to 16KB block sizes, enabling customers to eliminate database performance bottlenecks. I7i instances also support real-time, high-resolution performance statistics for the NVMe instance store volumes attached to them. To learn more, visit the detailed NVMe performance statistics page .

I7i instances are available in eleven sizes – nine virtual sizes up to 48xlarge and two bare metal sizes – delivering up to 100Gbps of network bandwidth and 60Gbps of Amazon Elastic Block Store (EBS) bandwidth.

Amazon EC2 M8a Instances now available in additional regions

By

Starting today, the general-purpose Amazon EC2 M8a instances are available in US East (N. Virginia) and Asia Pacific (Tokyo) regions. M8a instances are powered by 5th Gen AMD EPYC processors (formerly code named Turin) with a maximum frequency of 4.5 GHz, deliver up to 30% higher performance, and up to 19% better price-performance compared to M7a instances.

M8a instances deliver 45% more memory bandwidth compared to M7a instances, making these instances ideal for even latency sensitive workloads. M8a instances deliver even higher performance gains for specific workloads. M8a instances are up to 60% faster for GroovyJVM benchmark, and up to 39% faster for Cassandra benchmark compared to Amazon EC2 M7a instances. M8a instances are SAP-certified and offer 12 sizes including 2 bare metal sizes. This range of instance sizes allows customers to precisely match their workload requirements.

M8a instances are built using the latest sixth generation AWS Nitro Cards and ideal for applications that benefit from high performance and high throughput such as financial applications, gaming, rendering, application servers, simulation modeling, mid-size data stores, application development environments, and caching fleets.

To get started, sign in to the AWS Management Console. Customers can purchase these instances via Savings Plans, On-Demand instances, and Spot instances. For more information visit the Amazon EC2 M8a instance page .
