C. Scott Andreas updated CASSANDRA-11947:
-----------------------------------------
Component/s: Materialized Views
> Ability to create a Materialized View without primary key column that has '='
> relation
> --------------------------------------------------------------------------------------
>
> 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.
