Tyler Hobbs commented on CASSANDRA-7305:
A few minor comments:
* A space is missing in this error message: {{SELECT DISTINCT queries must
only request partition key columns and/or static columns(not %s)}}
* The {{select_distinct_test}} dtest method checks error messages that this
patch changes, so it now fails
* Make sure to update NEWS.txt describing the behavioral changes for existing
static columns users
Other than that, +1
CQL3, Static columns not returning rows if values are not set

Key: CASSANDRA-7305
URL: https://issues.apache.org/jira/browse/CASSANDRA-7305
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Patrick Callaghan
Assignee: Sylvain Lebresne
Fix For: 2.0.9
Attachments: 7305.txt
Just a quick note on static columns, if you create some cql rows using
clustered columns and don't provide a value for a static column, then
selecting the row key with the (null) static column won't return any rows.
create table statictest( a int, b text static, c text, PRIMARY KEY (a, c));
insert into statictest (a, c) values (1, 'test');
select a,b from statictest;
(0 rows)

It stems from the fact that for static columns we said that when only the partition key and static columns where selected, the user probably didn't meant to query the full partition, and so we only query the static part of the partition, hence the result above. In hindsight, I would agree that this is a mistake. We should make such query scan the whole partition the same way a selection of just the partition key still scan the full partition (and return as many results as there is rows). And we should extend DISTINCT so user can still query the static part efficiently. This is going to potentially break current users of static columns however (but they are new enough that it's probably fair game to fix early mistake rather than carry them down indefinitely).
