> MVs should validate gc grace seconds on the tables involved

>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9917
>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Aleksey Yeschenko
>             Fix For: 3.0 beta 1
>
>
> For correctness reasons (potential resurrection of dropped values), batchlog 
> entries are TTLs with the lowest gc grace second of all the tables involved 
> in a batch.
> It means that if gc gs is set to 0 in one of the tables, the batchlog entry 
> will be dead on arrival, and never replayed.
> We should probably warn against such LOGGED writes taking place, in general, 
> but for MVs, we must validate that gc gs on the base table (and on the MV 
> table, if we should allow altering gc gs there at all), is never set too low, 
> or else.
