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 the capability to add columns to existing multi-Region tables. With this launch, you can modify the schema of your existing multi-Region tables to add new columns. You only have to modify the schema of a multi-Region table in one of its replica regions and Keyspaces will replicate the new schema to the other regions where the table exists. Adding columns to multi-Region tables gives you the flexibility to update your data model seamlessly as your business and application needs evolve over time.
Support for adding columns to multi-Region tables is available in all commercial AWS Regions where AWS offers Amazon Keyspaces. If you’re new to Amazon Keyspaces, the Getting Started guide shows you how to provision a Keyspace and explore the query and scaling capabilities of Amazon Keyspaces.
