Multi-tenancy

In multi-tenant scenarios, the prefix cache key must include a unique tenant or session identifier; otherwise identical prefixes from different users will hit the same cache entry, causing context cross-talk.

The industry emphasizes that cache keys must be bound to a tenant or request identity, rather than being reused solely on the basis of content similarity.

In multi-tenant mode, the isolation boundary extends not only to networking and storage but also to intermediate state in GPU memory, and the KV cache is the most easily overlooked part of this.

In multi-tenant SaaS application scenarios, the core security objective is to achieve fine-grained row-level and column-level data isolation, and to push the isolation mechanism down to the data platform layer rather than keeping it at the application surface.

Multi-tenant isolation strategies include three types: schema-level isolation at the database layer, table-level isolation (via tenant_id field), and fully independent database instances

The project-level isolation design corresponds to the multi-tenant architecture pattern in software engineering, which avoids cross-contamination of different project contexts and facilitates team authorization by project.

Multi-tenancy is a foundational architectural pattern in cloud computing services, referring to multiple tenants sharing the same underlying computing resources and software instance while their data remains logically fully isolated from one another.
