AI engineering glossary · RAG vector search
What is multi-tenancy?
Multi-tenancy: Serving many separate customers from one shared system while keeping each one's data isolated. In RAG, this means every retrieval is restricted to the requesting tenant's documents, via namespaces or filters, to prevent data leaks between customers.
Multi-tenancy: an example
A SaaS help-desk tool serves 200 companies and tags every vector with its company id, enforcing that filter on each search.
