FAQ

How this task behaves

  • 01

    Can the AI delete old vectors from my index?

    No. This connector only handles inserting new data. You must manage deletions through your own database tools.

  • 02

    Does the AI create the embeddings for me?

    The AI can process text you provide, but it relies on the tools to insert the data. You should provide the embeddings or the text you want to be indexed.

  • 03

    Can I update existing records?

    No. The current tool is for inserting new documents and vectors into your collections.

  • 04

    Will this work with any vector database?

    No. This specific connector is built exclusively for DataStax Astra DB.

  • 05

    Do I need to manually run SQL commands?

    No. Once connected, you just tell your AI what to add, and it handles the insertion for you.
