Quickstart

Run this on Colab

This quickstart demonstrates how to insert data, generate vector embeddings, and perform a vector search to find similar data. Specifically, the example here loads data from a JSON file, uses the Astra-hosted NVIDIA embedding model to generate vector embeddings for the data, and then performs a vector search.

The Next steps section discusses how to insert other types of data, use a different embedding model, insert data with pre-generated vector embeddings, or skip embedding.

To learn more about vector databases and vector search, see Intro to vector databases and What is Vector Search?.

Create a database and store your credentials

  1. Sign in or create an Astra DB account.

  2. In the Astra Portal navigation menu, click Databases, and then click Create Database.

  3. For this quickstart, select:

    • Serverless (Vector) as the deployment type

    • Amazon Web Services as the provider

    • us-east-2 as the region

  4. Click Create Database.

    Wait for your database to activate. This can take several minutes. The Astra Portal will update once your database is active.

  5. Under Database Details, copy your database’s API endpoint.

  6. Under Database Details, click Generate Token, then copy the token.

  7. For this quickstart, store the endpoint and token in environment variables:

    • Linux or macOS

    • Windows

    export ASTRA_DB_API_ENDPOINT=API_ENDPOINT
export ASTRA_DB_APPLICATION_TOKEN=TOKEN
    set ASTRA_DB_API_ENDPOINT=API_ENDPOINT
    set ASTRA_DB_APPLICATION_TOKEN=TOKEN

Install a client

Install one of the Astra DB Data API clients to facilitate interactions with the Data API.

  • Python

  • TypeScript

  • Java

  1. Update to Python version 3.9 or later if needed.

  2. Update to pip version 23.0 or later if needed.

  3. Install the latest stable version of the astrapy package (1.5.2).

    pip install astrapy

  1. Update to Node version 18 or later if needed.

  2. Install the latest stable version of the @datastax/astra-db-ts package (1.5.0).

    For example:

    npm install @datastax/astra-db-ts

  • Maven

  • Gradle

  1. Update to Java version 17 or later if needed.

  2. Update to Maven version 3.9 or later if needed.

  3. Add a dependency to the latest stable version of the astra-db-java package (1.5.3).

    pom.xml
    <dependencies>
  <dependency>
    <groupId>com.datastax.astra</groupId>

Insert data to your database

The following script will insert data from a JSON file into a your database.

  1. Copy the script into your project.

  2. Download the quickstart_dataset.json sample dataset (76 kB). This dataset is a JSON array describing library books.

  3. Replace PATH_TO_DATA_FILE in the script with the path to the dataset.

  4. If needed, update the import path to the "connect to database" function from the previous section.

  5. Execute the script.

    Once the script completes, you should see a printed message confirming the insertion of 100 items.

Find data in your database

After you insert data to your database, you can search the data. In addition to traditional database filtering, you can perform a vector search to find data that is most similar to a search string.

The following script performs three searches on the sample data that you loaded in Insert data to your database.

1 This is the connectToDatabase function from the previous section.
2 If you changed the collection name in the previous script, change it in this script as well.

Next steps

For more practice, you can continue building with the database that you created here. For example, try inserting more data to the collection, or try different searches. The Data API reference provides code examples for various operations.

Upload data from different sources

This quickstart demonstrated how to insert data from a JSON file, but you can insert data from many sources, including CSV and PDF files.

  • If you can convert your data into JSON, you can use the example from this quickstart.

  • If your data is in unstructured files, such as PDF files, you can use the data loader or write a script to use the Unstructured.io integration to insert your data.

Use a different method to generate vector embeddings

This quickstart used the Astra-hosted NVIDIA embedding model to generate vector embeddings. You can also use other embedding models, or you can insert data with pre-generated vector embeddings (or without vector embeddings) and skip embedding.

  • To use a different embedding model, see Auto-generate embeddings with vectorize.

  • To insert pre-embedded data, you need to specify the vector dimensions and similarity metric instead of specifying the embedding provider. See the API documentation for collections.

  • To skip embedding, you can create a collection without any vector options. See the API documentation for collections.

Perform more complex searches

This quickstart demonstrated how to find data using filters and vector search. To learn more about the searches you can perform, see Find documents reference and Perform a vector search.

Use different database settings

For this quickstart, you need a Serverless (Vector) database in the Amazon Web Services us-east-2 region, which is required for the Astra-hosted NVIDIA embedding model integration.

For production databases, you might use different database settings.

For more information, see Astra DB Serverless database regions and maintenance schedules and Create a database.

For more examples, see the integration guides, code examples, and tutorials.
