Using Astra DB as the vector store for a DataStax docs RAG chat

For Astra Docs Chat , the subject matter is Astra DB Serverless: using Astra as the vector store was the natural fit, and Langflow’s DataStax bundle already wired up ingest and search components.

Collection setup ¶

Production values in the Langflow flow:

Field	Value
Collection name	`datastax_astra_docs`
Keyspace	`default_keyspace`
Same collection	Ingest flow writes; chat flow reads

First ingest into an empty collection is simplest. Re-runs append unless you configure deletion/upsert fields in the AstraDB component.
