---------------------------------------------

bq. I was trying to explain the issue that you are here as well =E2=80=93 n=
ot how it currently works.

Cool then, sorry the confusion. I guess the one small that is not implement=
ed though, is that you currently only allow a single column that is not a b=
ase table PK in the MV pk, while we could allow as many as we want as long =
as we take the min TTL. Or is that also already implemented?

> Local indexes are suitable for low-cardinality data, where spreading the =
index across the cluster is a Good Thing.  However, for high-cardinality da=
ta, local indexes require querying most nodes in the cluster even if only a=
 handful of rows is returned.
