-------------------------------------------------------------------
I don't see updated CQL.textile for CREATE MV on the branch. Coming soon?
Also, the comment for CREATE MV in CQL.g does not quite match the actual syntax:
1. Missing the IF NOT EXISTS clause.
2. Has parentheses around the <columns> list, but SELECT does not have that.
3. Unclear whether AS or functions are supported in the column name list, but
selectStatement would certainly allow that.
4. Has FROM (<columnName>), which should be FROM <CF>, I think.

> Local indexes are suitable for low-cardinality data, where spreading the
> index across the cluster is a Good Thing. However, for high-cardinality
> data, local indexes require querying most nodes in the cluster even if only a
> handful of rows is returned.
