I'm not sure how interleaved tables help you with multi-tenancy, but I'd be curious to find out. If, by multi-tenancy, you mean sharing a CRDB cluster between different applications or different instances of the same application, or different organizations all-together (say, in a hosted cluster that 3rd parties get access to), we don't have particular support for any of these. If each client is configurable with a user and a database, you can created different users/databases for each one and set the appropriate permissions. You can even set different placement options for the different databases if you want some in Asia and some in Africa. When it comes to usage accounting, resource isolation, specific monitoring, there's nothing built-in at the moment.
