There is neither, and DNS records obtained through TCP /are/ cached.

Or, more to the point, answers are cached (or not, depending on the
cache-related settings in dnsmasq) regardless of whether they were
obtained through UDP or TCP.

What made you believe that answers obtained through TCP would not be
cached?

Amicalement,
