Agent vector databases

Vector databases store embeddings and enable semantic retrieval for Agent knowledge.

In Budibase, vector databases are configured in Workspace Settings > Connections > Knowledge bases and then assigned to each Agent in the Knowledge tab.

Supported provider

Currently we only support pgvector as a provider.

Configure a vector database

1. Open Settings
2. Go to Connections > Knowledge bases
3. In Vector databases, click + Vector database
4. Enter connection settings:
   • Name
   • Provider (defaulted to pgvector)
   • Host
   • Port
   • Database
   • User
   • Password
5. Save and confirm the database appears in the list

Attach a vector database to an Agent

1. Open your Agent
2. Go to the Knowledge tab
3. Select a Vector database
4. Select an Embedding model
5. Save

After both are selected, you can tune:

• Minimum similarity
• Chunks to retrieve

You can then add files/knowledge content in the same area to support retrieval.
