             Summary: add a cardinality function for collection types ( CQL3 )
                 Key: CASSANDRA-5313
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5313
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Ahmet AKYOL


Currently , cql3 doesn't provide a cardinality function for collection types. 
It'll be great to have one:

{code}
select content, cardinality(like_set),cardinality(dislike_set) from comments;
{code}

or size as keyword
{code}
select content, size(like_set),size(dislike_set) from comments;
{code}

Something similar in SQL is [cardinality of nested 
tables|http://www.techonthenet.com/oracle/functions/cardinality.php] .
