What is DataStax Astra?

DataStax Astra, built on the best distribution of Apache Cassandra™, provides the ability to develop and deploy data-driven applications with a cloud-native service, without the hassles of database and infrastructure administration.

By automating tuning and configuration, DataStax Astra radically simplifies database operations.

Limits help enforce best practices by defining parameters for operations, such as table number and column size limits, ensuring the database operates with consistent performance and maintains cluster health.

Each Astra database on a paid tier employs a single capacity unit (CU) by default, which represents three database nodes that are grouped together. A single CU represents three replicas of approximately 500 GB of user data. CUs ensure high availability by implementing a consistent replication factor that is acceptable for development and production workloads.

To ensure that an Astra database doesn't exceed capacity, you can expand the database by adding CUs.

Developers can easily resize resources as their needs grow and change, and park databases when not in use to save costs and pay for only storage.
