Description

Filtering MVs by non-pk column was originally introduced on CASSANDRA-10368 but disallowed on CASSANDRA-13798 because it may not properly support updates to individual columns in some cases, unless the flag cassandra.mv.allow_filtering_nonkey_columns_unsafe=true is passed (it's safe to use only on append-only workloads).

Proper support to updates on filtered columns requires CASSANDRA-13826, so this ticket is to re-enable it after that is done.
