Astra DB Serverless release notes provide information about new and improved features, known and resolved issues, and bug fixes.

20 February 2024

The DataStax Data API 1.0.1 release optimized its limits:

  • The maximum path length increased from 250 to 1,000. That limit is the total for all segments, including any dots (.) between properties in a path.

  • The maximum size of an entire batch of documents submitted via an insertMany or updateMany command increased from five million to 20 million characters.

See Data API limits for the full list of limits.

For information about other recent Data API 1.0.1 changes, see the CHANGELOG in the open-source stargate/jsonapi GitHub repo.

17 January 2024

A new Data API and revamped developer experience make Astra DB Serverless an even better fit for developing production generative AI and retrieval-augmented generation (RAG) applications. For more about this release, see the blog post or join our YouTube livestream on January 24 with our partners from Vercel and LangChain.

This release includes these improvements:

The new Data API

The new Data API is a schema-less, document-based, modern API that provides easy and intuitive access to both structured and unstructured data. The API leverages the scalability, performance, and real-time indexing capabilities of Apache Cassandra® to provide a clear path for GenAI application development, from initial data loading and the first line of code to production. Developers can execute vector search queries and apply complex document filtering—and combine the two to get the most relevant results possible.

The Data API is an entry point for Astra DB Serverless to integrate with the GenAI ecosystem, which includes tools like LangChain, LlamaIndex, Google Vertex AI, Amazon Bedrock, and others.

New client libraries

The new client libraries for Python, TypeScript, and Java simplify the development process with Astra DB Serverless. With just an API endpoint and token, developers can quickly add the most performant and scalable vector store to their next GenAI application.

Data Explorer in the Astra Portal

With the Data Explorer, developers can visualize similarity search scores and conduct vector-based searches with a ranked list of up to 100 results, based on similarity. This feature is particularly beneficial for RAG and AI agent use cases, allowing for refined search results. The Data Explorer also supports hybrid search filters, enabling more versatile and powerful data querying capabilities.

Focused and practical documentation

The Astra DB Serverless documentation is tailored to meet developers at each specific stage of development, providing relevant and essential information without unnecessary details.

14 November 2023

Astra Portal offers a new vector database experience. To try it, click Enable Preview in the Astra Portal.

The new experience includes:

  • Python, TypeScript, and Java clients for Serverless (Vector) databases.

  • New UIs for Database Metrics, Database Loader, and Database Explorer.

  • Enhanced documentation about the new vector experience.

Start in Astra Portal and see the Astra DB Serverless documentation.

Existing users of the JSON API and Mongoose public preview can toggle between the existing and new experiences. In Astra Portal, use the Enable Preview or Disable Preview buttons in the top banner.

5 September 2023

Analyzers are now available. Using analyzers with vector search allows you to create a hybrid search that includes your keyword and a vector.

18 July 2023

Astra Vector Search is generally available. Astra DB Serverless supports Vector Search to aid in developing Generative AI and Machine Learning applications.

  • Changes to database creation accommodate new vector-enabled regions.

  • Removal of Public preview designation for serverless Astra databases with Vector Search.

26 June 2023

Updated Organization Settings simplify managing users, roles, tokens, billing, and security.

25 June 2023

Astra Portal supports adding Splunk, Pulsar/Streaming, or Datadog as a destination for exported Astra DB Serverless health metrics. Those destinations were already supported via the DevOps API. Additional destinations are provided.

22 June 2023

Added two caller modes in the Astra DB Serverless Plugin for HashiCorp Vault 2.0.0 release. For details about the standard and sidecar caller modes, and updated vault commands, see the plugin’s documentation in its GitHub repo.

07 June 2023

Astra Vector Search is in public preview for Astra DB Serverless. 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.

27 February 2023

  • Integrations are now embedded within the Astra Portal.

  • You can now expand and collapse the left navigation.

  • The Astra Portal is now designed to also fit a tablet or laptop.

02 February 2023

Added Datadog as a supported destination of Astra DB Serverless Serverless database health metrics, via the DevOps v2 API. Exporting these metrics to Datadog is not supported via the Astra Portal at this time.

31 January 2023

Released DataStax Zero Downtime Migration 2.2.0, which added the zdm_proxy_cluster_config.yml file to contain all the configuration variables for Origin and Target. Prior to version 2.2.0, the variables were in the zdm_proxy_core_config.yml file. The change is backward compatible.

13 January 2023

Zero Downtime Migration (ZDM) has released version 2.1.0. By default, ZDM Proxy now sends heartbeats after 30 seconds of inactivity on a cluster connection.

05 January 2023

Lightweight Transactions (LWTs) now support EACH_QUORUM and SERIAL consistency levels.

03 January 2023

Astra DB Serverless adds support on AWS for the Payment Card Industry Data Security Standard 3.2.1 (PCI DSS).

To create and use Astra DB Serverless on AWS that comply with PCI DSS, please contact your DataStax Account Executive or email sales@datastax.com.

Previous releases
14 December 2022

Published the Astra Command Line Interface (Astra CLI) 0.2 documentation. Astra CLI provides a one-stop shop for managing your Astra resources through scripts or commands in your local terminal.

05 December 2022

Added Splunk and Pulsar as supported destinations of Astra DB Serverless exported health metrics, via the DevOps API.

10 November 2022

Released the General Availability (GA) version of Astra DB Serverless Plugin for HashiCorp Vault. The GA version includes new support for dynamic token management. See our Astra DB Serverless Plugin for HashiCorp Vault documentation in the plugin’s GitHub repo.

Specifically, you can:

  • Define a default lease time

  • Create new tokens with lease settings

  • List tokens by each one’s Client ID

  • View lease details

  • List all leases

  • Renew a lease

  • Revoke a token/lease before the lease expires

  • Delete a token

18 October 2022

Using DataStax Zero Downtime Migration (ZDM) 2.0 allows you to migrate to Astra DB Serverless from Apache Cassandra® and DataStax Enterprise (DSE). For example, you can use ZDM to migrate your client applications and data from Cassandra 3.11.x directly to cloud-native Astra DB Serverless.

This suite of tools allows for zero downtime migration only if your database meets the minimum requirements. If your database does not meet these requirements, you can complete the migration from Origin to Target, but downtime might be necessary to finish the migration.

13 October 2022

Launched renamed, aggregated health metrics. You can export these metrics to a third-party system such as Amazon CloudWatch, Kafka, and Prometheus, and use tools such as Grafana Cloud to visualize the metrics.

21 July 2022
