In this post we walk through the steps to setup CQL Replicator and migrate a table from self-managed Cassandra cluster to Amazon Keyspaces. We demonstrate how to set up, run, and shut down the CQLReplicator job using command line tooling and observe changes flowing through the pipeline in Amazon CloudWatch.

This post discusses why DML auditing is important for some organizations, and walks you through setting it up for Amazon Keyspaces. Then, using an example, we show how native integration between Amazon Keyspaces and CloudTrail makes it straightforward to record and analyze audit trails (change events) from multiple tables in a keyspace without the use of additional tools.

PayU provides payment gateway solutions to online businesses through its award-winning technology and has empowered over 500 thousand businesses, including the country’s leading enterprises, e-commerce giants, and SMBs, to process millions of transactions daily. In this post, we outline how at PayU, we use Amazon Keyspaces (for Apache Cassandra) as the feature store for real-time, low-latency inference in the payment flow.

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra-compatible database service. With Amazon Keyspaces, you can run your Cassandra workloads on AWS using the same Cassandra application code and developer tools that you’re currently using.

Today, we are introducing support for frozen collections in Amazon Keyspaces. With this launch, you can use the frozen keyword and store collection data types (like lists, sets, and maps) as a single, immutable value. In this post, we discuss the benefits and use cases of this new feature, and demonstrate how to create and use frozen collections in Amazon Keyspaces.

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra-compatible database service. With Amazon Keyspaces, you can run your Cassandra workloads on AWS using the same Cassandra application code and developer tools that you use today. Today we are introducing Amazon Keyspaces Multi-Region Replication. Amazon Keyspaces Multi-Region Replication is a new […]

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra-compatible database service. With Amazon Keyspaces, you can run your Cassandra workloads on AWS using the same Cassandra application code and developer tools that you use today. You don’t have to provision, patch, or manage servers, and you don’t have to install, […]

The Amazon Keyspaces team had a great time meeting with many of you at AWS re:Invent 2022. It was particularly exciting to experience re:Invent at its peak in-person attendance. The team enjoyed listening to your feedback and use cases, and understanding what you want us to build next. We work backwards from these conversations and feedback […]

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 […]
