Aleksey Yeschenko updated CASSANDRA-9672:
-
Description:
Many users have tables that rely on TTL entirely - no deletes, and only fixed
TTL value.
The way that default ttl works now, we only apply it if none is specified.
We should provide an option that would *enforce* the specified TTL. Not
allowing ttl-less {{INSERT}} or {{UPDATE}}, not allowing ttl that's lower or
higher than the default ttl, and not allowing deletes.
That option when enabled ({{force_default_ttl}}) should allow us to drop more
tables during compaction and do so cheaper. Would also allow the DBAs to
enforce the constraint in a guaranteed manner.

Provide a per-table param that would force default ttl on all updates
