[jira] [Commented] (CASSANDRA-3513) CQL Schema metadata does not contain Type information for the key unless the key is selected

    [ https://issues.apache.org/jira/browse/CASSANDRA-3513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156228#comment-13156228 ] 

Thorsten von Eicken commented on CASSANDRA-3513:
------------------------------------------------

One issue I see with this is how do you do a column slice across multiple rows while getting the key? Maybe I'm mistaken, but it seems to me that the following query is not legal CQL:
SELECT key, from_col..to_col FROM ... WHERE indexed_column = value;
Is this something that will be no longer supported?

> The CQL ResultSchema does not contain type information for the key unless the key is actually part of the CQL query. It's available in the column family schema but that's what we're trying to avoid by having a ResultSchema in the first place.
