[jira] [Commented] (CASSANDRA-2396) Allow key name metadata

    [ https://issues.apache.org/jira/browse/CASSANDRA-2396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13012266#comment-13012266 ]

---------------------------------------

Unrelated to this ticket but stumbled upon, moved convertToCFMD(thrift CfDef) into CFMD. It had no business being in CassandraServer.

> CASSANDRA-2311 allows typed keys. We also want to allow giving keys a name (that would need to conform to the CF comparator). This is required for Hive support; HIVE-1434 currently stores that metadata in an external repository but it would be cleaner to keep it in CFMetadata. This would allow CQL to support using the key name in select and where clauses, reducing the impedance mismatch between JDBC/CQL and JDBC/Hive.
