Knowledge Base
Query, upsert, and delete vectors, and manage datasources from a workflow.
Knowledge Base blocks sit in the builder palette under kb. They search and update the same knowledge bases you attach to agents for RAG.
Shared graph rules are on Workflows. Read only stores allow query and list, not upsert or delete. Strict stores require metadata that matches the meta fields you defined.
Add Datasource and Refresh Datasource queue work in the background. The graph continues before vectors are ready. Check status with Get Datasource or List Datasources before you Query.
