>                 Key: CASSANDRA-11947
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11947
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Materialized Views
>            Reporter: Nimi Wariboko Jr.
>            Priority: Major

> I have a use case where I'd like to create a materialized view where one of the columns
is filtered on a '=' relation and the primary key for that materialized view doesn't include
that column.
> Example:
> {code}
> CREATE TABLE analytics (
>   resourceId text,
>   country text,
>   date timestamp,
>   clicks int,
>   PRIMARY KEY(resourceId, date, country)
> );
> CREATE MATERIALIZED VIEW analytics_ww AS
>        SELECT * FROM analytics
>        WHERE country = 'WW'
>        PRIMARY KEY (resourceId, date);
> {code}
> This way I can have a table filtered on a high cardinality column, and I don't also have
to specify that column, even though I already know thats the only value in the view.
