-------------------------------------------

How would you add this to the actual configuration language?

> When using one data center for hadoop/analytics, one as a canonical store and for serving high volume writes, and possibly even one for low-latency reads, the tuning requirements are dramatically different on the same column family.
> I suspect being able to configure caching on just one datacentre would really make a difference.
