Ahmet AKYOL created CASSANDRA-5313: -------------------------------------- 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] . -- This message is automatically generated by JIRA.
