C. Scott Andreas updated CASSANDRA-9672:
----------------------------------------
Component/s: Distributed Metadata
> Provide a per-table param that would force default ttl on all updates
> ---------------------------------------------------------------------
>
> Key: CASSANDRA-9672
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9672
> Project: Cassandra
> Issue Type: Improvement
> Components: Distributed Metadata
> Reporter: Aleksey Yeschenko
> Priority: Minor
>
> 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.
