Astra DB: Serverless vector database for scalable Generative AI workloads
Browse Astra DB developer guides, tutorials, and API references. Build an AI-ready serverless vector database in minutes using Astra Portal.
DataStax Astra DB is a serverless vector database that’s perfect for managing mission-critical AI workloads. It’s built on Apache Cassandra®, making Astra DB a highly scalable, reliable database technology. This makes it a powerful all-in-one data storage solution, ideal for Generative AI projects.
Astra Vector Search efficiently finds highly relevant and similar context in large language models (LLMs). Vector Search captures semantics in a way that eclipses term-based relevance methods. The Vector Search data can be read with CQL or cassIO.
To learn more, see Astra Vector Search, and get started in Astra Portal.

Astra DB provides the easiest, most cost-effective solution for implementing Cassandra and DataStax Enterprise workloads in the cloud.
Astra DB is designed to be secure by default, with built-in security controls that integrate with your existing security policies and protocols.
Connect to your database using APIs, native drivers, or the command line.
Migrate applications from any CQL-based cluster (Apache Cassandra®, DSE, Astra DB, or any type of CQL-based database) to any other CQL-based cluster, without any interruption of service to the client applications and data.
Astra DB includes Stargate, an open-source, data API gateway that sits between your application and the database. Every database you create automatically has gRPC, GraphQL, REST, a Document (schemaless JSON) API, alongside native driver (CQL) coordinators.
Extend Astra DB with additional capabilities through integrations with other popular technologies like Temporal, Feast, and Grafana.
