---------------------------------------------
Summary: 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
Reporter: Nimi Wariboko Jr.
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.
