--------------------------------------------
Summary: MVs should validate gc grace seconds on the tables
involved
Key: CASSANDRA-9917
URL: https://issues.apache.org/jira/browse/CASSANDRA-9917
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: T Jake Luciani
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.
