Subject [jira] [Commented] (CASSANDRA-2474) CQL support for compound columns
Date Mon, 13 Jun 2011 15:25:51 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13048598#comment-13048598
] 

Jonathan Ellis commented on CASSANDRA-2474:
-------------------------------------------

Summary: general agreement that "SELECT parent:column" notation is a bad fit. Some alternatives
are presented. Most would require a Cassandra-aware Hive metastore to get the same syntax
for Hive and Cassandra; Hive is primarily concerned with "select *" but Cassandra needs an
effective way of representing "give me all the subcolumns for parent foo" (which is where
the current HQL syntax is inadequate).

> For the most part, this boils down to supporting the specification of compound column
names (the CQL syntax is colon-delimted terms), and then teaching the decoders (drivers) to
create structures from the results.
