Cassandra partial partition key

问题

CREATE TABLE footable (
    column1 text,
    column2 text,
    column3 text,
    column4 text,
    PRIMARY KEY ((column1, column2))
)

In the example above which I got from Querying Cassandra by a partial partition key, is it possible to use condition on the 1st partition key and select all condition on 2nd partition key?

Example cql statement may look like this:

select * from footable where column1 = 'name' and column2 ALL;

Is there some sort of querying like this in Cassandra?

回答1:

No. To support that query, (in your table definition) you would have to modify the PRIMARY KEY to only use only column1 as the partition key, and designate column2 as a clustering key:

PRIMARY KEY ((column1), column2)

Then this query would return your desired results:

select * from footable where column1 = 'name';
