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

I'm making the changes you've listed, hope to have them ready shortly.

About the {{CONTAINS}} restriction on the Clustering columns, I am most likely missing something,
but at least so far the collection types aren't allowed to be a part of the primary key at
all, even as a Clustering Column: {{Invalid collection type for PRIMARY KEY component b}}
whenever {{b}} is a collection type. On the other half, it's not possible to use contains
on non-collection types: {{Cannot use CONTAINS on non-collection column b}}.

>
> Since CASSANDRA-6377 queries without index filtering non-primary key columns are fully
supported.
> It makes sense to also support filtering on clustering-columns.

> CREATE TABLE emp_table2 (
> empID int,
> firstname text,
> lastname text,
> b_mon text,
> b_day text,
> b_yr text,
> PRIMARY KEY (empID, b_yr, b_mon, b_day));
> SELECT b_mon,b_day,b_yr,firstname,lastname FROM emp_table2
> WHERE b_mon='oct' ALLOW FILTERING;
> {code}
