Serverless database overview
Astra DB Serverless is a fully managed serverless database-as-a-service (DBaaS), powered by Apache Cassandra®, an open-source NoSQL distributed database.
Astra DB Serverless offers two types of serverless databases: Serverless (Vector) and Serverless (Non-Vector).

Database terminology
Depending on your background and experience, you might be familiar with various terminology for database components. For example, Apache Cassandra® users might use terms like clusters, keyspaces, tables, and columns. Whereas other developers might use terms like namespaces, collections, documents, and fields to refer to functionally similar or identical components.
In Astra DB, the terminology you encounter depends on the database types and features that you use. The following table explains some of these terms. Each set of terms describe functionally similar components, but these components are not always exact equivalents. For example, a single field of vector data doesn’t necessarily translate directly to a single column of non-vector data.

Namespace |
Keyspace |
A container for one or more collections or tables within a database. The Astra Portal uses namespace in Serverless (Vector) databases and keyspace in Serverless (Non-Vector) databases.
However, the name of the default namespace for each Serverless (Vector) database is The Data API and clients for Astra DB Serverless use namespace. You can’t use the Data API to manage Serverless (Non-Vector) databases. For more information, see API reference overview and Databases reference. |
Collection |
Table |
A container for data within a database. The Astra Portal uses collection in Serverless (Vector) databases and table in Serverless (Non-Vector) databases. The Data API and clients for Astra DB Serverless use collection. Although you can store non-vector data, including CQL table data, in a collection, the Astra Portal and Data API still use the terms collection and namespace. If you use CQL to |
