Aleksey Yeschenko commented on CASSANDRA-6477:
----------------------------------------------
bq. I think that SelectStatement shouldn't be checking the SELECT on the base
table; it's possible for a less restrictive set of values to be present in the
MV, so the set of permissions should be accordingly more granular.
Oh, but it definitely should be, since there will be at least one column from
the base table here, and authz works on a white-list basis.

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