Multi-Tenancy Vector Search with millions of tenants

Weaviate v1.20 introduces native multi-tenancy support that scales to millions of tenants with tens of thousands of active tenants per node. This feature is designed for large-scale enterprise users and focuses on compliance, smooth UX, and efficient resource management. It enables isolation between tenants, fast querying, GDPR-compliant deletes, and massive scale support. The upcoming release also introduces the ability to distinguish between active and inactive tenants, allowing businesses to save on infrastructure costs for users who aren't currently active.
