Caleb Rackliffe commented on CASSANDRA-17212:
---------------------------------------------

Looking through the proposals so far, I find [~benedict]'s structure 
[here|https://github.com/belliottsmith/cassandra/blob/5f80d1c0d38873b7a27dc137656d8b81f8e6bbd7/conf/cassandra_nocomment.yaml#L160]
 most appealing. In that case, I think the CASSANDRA-14557 replication bits we 
want would look something like...

{noformat}
limits:
...
    replication:
        minimum: 3
        default: 1
{noformat}

On the subject of a global {{enable}} flag, that feels most appropriate for 
individual categories or limit concepts. Most of its value is not having to 
come up with special/sentinel values that disable something. (i.e. You can 
leave something both disabled and w/ a reasonable value if enabled in the 
config as documentation.)
