> One of the goal of CQL3 is that client library should not have to parse queries to provide a good experience. In particular, that means such client (that don't want to parse queries) won't be able to allow the user to define a specific default read/write consistency level per-CF, forcing user to specific the consistency level with every query, which is not very user friendly.
> This ticket suggests the addition of per-cf default read/write consitency level. Typically the syntax would be:
> {noformat}
> CREATE TABLE foo (...)
> WITH DEFAULT_READ_CONSISTENCY = QUORUM
>  AND DEFAULT_WRITE_CONSISTENCY = QUORUM
> {noformat}
