How does Qdrant support multi-tenancy?

Qdrant supports multi-tenancy through two main patterns: one collection per tenant, which gives strong isolation at the cost of overhead for many small tenants, or a shared collection with tenant identifier in the payload plus filter on every query. For the shared pattern, Qdrant recommends a payload index on the tenant field and using group-by or shard-key sharding to colocate tenant data on specific shards. This reduces query latency because searches touch only shards containing the tenant's data.
