What tools does DataStax Astra include?

  • Astra REST API: Use the DataStax Astra REST API to create an authorizationauthorization - Process of establishing permissions to database resources through roles. token and begin interacting with your databasedatabase - A group of distributed instances for storing data. Each paid Astra database has at least three instances..
  • CQLSH: Each Astra database includes an integrated CQL shellCQL shell - The Cassandra Query Language shell (cqlsh) utility. for interactive Cassandra Query Language (CQL) commands. Use CQLSH to create tables, insert data, and modify data in your keyspacekeyspace - The defining container for replication, similar to a schema in a relational database. All tables belong to a keyspace. Each keyspace can contain as many as 200 tables..
  • DataStax Developer Studio: Each Astra database embeds a DataStax Developer Studio instance that is automatically configured for interactive CQL commands. Kickstart development with the included Developer Studio notebooks.
  • DataStax Bulk Loader: Use DataStax Bulk Loader (dsbulk) to load and unload data into your Astra database. You can load data from a variety of sources and unload data from DSE or DDAC databases for transfer, use, or storage of data.
  • Metrics dashboards: Use the integrated metrics dashboards to view health metrics that include information regarding latency and throughput to the database. These metrics provide insights into the performance of the database and how workloads are distributed.

Which cloud regions are currently available?

DataStax Astra supports single-region deployments only. These regions vary based on the selected cloud provider and more are added over time. The regions that are currently available can be seen on the create database screen. Within a regionregion - A group of related nodes configured together within a database for replication purposes. A region is virtual datacenter hosted on your selected cloud provider. Using separate regions prevents transactions from being impacted by other workloads and lowers latency. Depending on the replication factor, data can be written to multiple regions. Regions cannot span physical locations. A region in Astra is the same concept as a "datacenter" in Apache Cassandra™ or DataStax Enterprise., data is replicated across three availability zones to ensure high availability.

You can create up to 5 databases per region, and add a total of 20 capacity units (CUs) per database (10TBs). To adjust the capacity unitcapacity unit - Represents three database instances grouped together with three replicas. limits or request new regions contact DataStax Support.
