-------------------------------------------------------------------
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}}.

> Key: CASSANDRA-11310
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11310
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Benjamin Lerer
> Assignee: Alex Petrov
> Labels: doc-impacting
> Fix For: 3.x
>
>
> Since CASSANDRA-6377 queries without index filtering non-primary key columns
> are fully supported.
> It makes sense to also support filtering on clustering-columns.
> {code}
> 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}
