Category: Amazon Keyspaces (for Apache Cassandra)

Amazon Web Services (AWS) customers migrating their Apache Cassandra workloads to Amazon Keyspaces (for Apache Cassandra) have rediscovered Cassandra’s lightweight transactions (LWT) API. Amazon Keyspaces LWTs have consistent performance, reliable scalability, and improved isolation that allow developers to use LWTs with mission critical workloads. With Amazon Keyspaces, LWTs have similar single digit millisecond latencies as […]

In this post, we walk you through an example of how you can use Amazon Keyspaces (for Apache Cassandra) with Amazon Elastic Container Service (Amazon ECS) to modernize your existing Cassandra workloads. These services use open standards that allow customers to migrate their existing workloads to take advantage of these services’ fully managed capabilities and […]

Time to Live (TTL) is a widely used feature in Apache Cassandra. TTL helps developers manage storage costs and simplify application logic by expiring data automatically at a specified time. For example, you can use TTL in time series workloads to remove older data automatically to save on storage costs. You also can use TTL […]

Managing virtual machine images that you standardize through configuration, consistent security patching, and hardening (also called “golden images”) is a time-consuming task. System administrators and database administrators responsible for these tasks have to define the characteristics of these images (such as which software to pre-install, which versions to use, and which security configurations to apply). […]

AWS customers use Amazon Keyspaces (for Apache Cassandra) to modernize their Cassandra workloads. Keyspaces offers customers scalability and fast performance to provide users a great end-user experience. Amazon Keyspaces is a scalable, highly available, and managed Apache Cassandra-compatible database service.

The COVID-19 pandemic presented enterprises with various challenges. Enterprises notably need to safeguard employees, partners, and customers when they return to the office. Holistic workforce strategies require a combination of preventative screening tools and detailed contact tracing solutions. PricewaterhouseCoopers LLP (PwC) quickly responded and adapted to develop Check-In, powered by AWS. Check-In provides companies with […]

In this post, we build an end-to-end data model for an internet data consumption application. Data modeling provides a means of planning and blueprinting the complex relationship between an application and its data. Creating an efficient data model helps to achieve better query performance. An inefficient data model can slow development and performance, increase costs, […]

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra-compatible database service that enables you to run Cassandra workloads more easily by using a serverless, pay-as-you-go solution. With Amazon Keyspaces, you don’t have to worry about configuring and optimizing your Cassandra cluster for your mission-critical, operational workloads. Amazon Keyspaces provides you […]

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and fully managed Cassandra-compatible database service. Amazon Keyspaces helps you run your Cassandra workloads more easily by using a serverless database that can scale up and down automatically in response to your actual application traffic. Because Amazon Keyspaces is serverless, there are no clusters or […]

The Cassandra Query Language Shell (cqlsh) is an open-source command line shell that you can use to run CQL commands and perform database administrative tasks, such as creating and modifying tables. You can use cqlsh to get started with Amazon Keyspaces (for Apache Cassandra)—a scalable, highly available, managed Cassandra-compatible database—by loading data from a CSV […]
