[jira] [Comment Edited] (CASSANDRA-5138) Provide a better CQL error
when table data does not conform to CQL metadata.
[ https://issues.apache.org/jira/browse/CASSANDRA-5138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13772031#comment-13772031 ]

-------------------------------------------------------------------------
Another related issue. This check seems to make it impossible to insert proper records into CQL3 tables via Thrift, since it bails out on an attempt to write a column with an empty last component.
CREATE TABLE test (
id text,
attr text,
value text,
PRIMARY KEY (id, attr)
);
The storage column structure for the table would be:
|<key>|{<attr>,}|[empty]
|<key>|{<attr>,"value"}|<value>
There is no way to insert the first column (record demarcation) as it fails with "Invalid cell for CQL3 table test. The CQL3 column component () does not correspond to a defined CQL3 column"
