Amazon Keyspaces (for Apache Cassandra) announces frozen collections in AWS GovCloud (US) Regions
Amazon Keyspaces (for Apache Cassandra) is a scalable, serverless, highly available, and fully managed Apache Cassandra-compatible database service that offers 99.999% availability.
Today, Amazon Keyspaces added support for frozen collections in the AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions. With support for frozen collections, the primary keys in your tables can contain collections, allowing you to index your tables on more complex and richer data types. Additionally, using frozen collections, you can create nested collections. Nested collections enable you to model your data in a more real-world way and efficient manner. The AWS console extends the native Cassandra experience by giving you the ability to intuitively create and view nested collections that are several levels deep.
Support for frozen collections is available in all commercial AWS Regions and the AWS GovCloud (US) Regions where AWS offers Amazon Keyspaces.
