[jira] [Commented] (CASSANDRA-4762) Support multiple OR clauses for CQL3 Compact storage

["Sylvain Lebresne (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-4762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13469459#comment-13469459 ] 

Sylvain Lebresne commented on CASSANDRA-4762:
---------------------------------------------

Agreed, though I suppose for the query you meant something like:
{noformat}
SELECT * FROM test WHERE 
  name IN ('a','b') and
  tdate IN ('2010-01-01','2011-01-01') and
  tdate2 IN ('2010-01-01','2011-01-01') and
  tdate3 > '2010-01-01'
{noformat}
Otherwise, it's more a 2ndary index query is that doesn't have much to do with CASSANDRA-3885.

Also, there is no reason to make that work only for compact storage.

> Given CASSANDRA-3885
> It seems it should be possible to store multiple ranges for many predicates even the inner parts of a composite column.
> They could be expressed as a expanded set of filter queries.
> example:
> {code}
> CREATE TABLE test (
>        name text,
>        tdate timestamp,
>        tdate2 timestamp,
>        tdate3 timestamp,
>        num double,
>        PRIMARY KEY(key,tdate,tdate2,tdate3)
>      ) WITH COMPACT STORAGE;
> SELECT * FROM test WHERE 
>   name IN ('a','b') and
>   tdate IN ('2010-01-01','2011-01-01') and
>   tdate2 IN ('2010-01-01','2011-01-01') and
>   tdate3 IN ('2010-01-01','2011-01-01') and
>   num > 1.0
> {code}
