Each vector can carry a namespace string, and a query can restrict itself to one namespace. This is a separate mechanism from metadata filtering: the namespace is its own query option, it needs no metadata index, and it is generally the cheaper way to segment an index by tenant, language or document set.
An index supports up to 1,000 namespaces. A query names at most one of them, so searching across two tenants means two queries and a merge in application code. The namespace is fixed per vector at write time, and changing it requires upserting the whole vector. Because segmenting by namespace narrows the candidate set before the search runs, it also gives better recall for small tenants than filtering results afterwards.
