Subject [jira] [Commented] (CASSANDRA-11907) 2i behaviour is different in different versions
Date Thu, 23 Jun 2016 21:04:16 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11907?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15347178#comment-15347178

Alex Petrov commented on CASSANDRA-11907:
-----------------------------------------

2.1 patch is quite different from the other ones, as it was pre-[CASSANDRA-7981]. I've tried
to keep the logic similar to current one: if there's a slice restriction (single or multiple),
the next restriction has to use filtering. Previously, one of the columns ({{c2}} in previous
comment) was removed from {{restrictedColumns}}, but slice bounds were not really taking it
into account, so we were getting extra results.

Comments on {{2.2}} and {{3.0}} are same.

> 2i behaviour is different in different versions

>                 Key: CASSANDRA-11907
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11907
>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Tommy Stendahl
>            Assignee: Alex Petrov
>
>  I think I have found more cases where 2i behave different in different Cassandra versions,
CASSANDRA-11510 solved one such case but I think there are a few more.
> I get one behaviour with 2.1.14 and Trunk and I think this is the correct one. With 2.2.7
and 3.0.6 the behaviour is different.
> To test this I used ccm to setup one node clusters with the different versions, I prepared
each cluster with these commands:
> {code:sql}
> CREATE KEYSPACE test WITH replication = {'class': 'NetworkTopologyStrategy', 'datacenter1':
'1' };
> CREATE TABLE test.table1 (name text,class int,inter text,foo text,power int,PRIMARY KEY
(name, class, inter, foo)) WITH CLUSTERING ORDER BY (class DESC, inter ASC);
> CREATE INDEX table1_power ON test.table1 (power) ;
> CREATE TABLE test.table2 (name text,class int,inter text,foo text,power int,PRIMARY KEY
(name, class, inter, foo)) WITH CLUSTERING ORDER BY (class DESC, inter ASC);
> CREATE INDEX table2_inter ON test.table2 (inter) ;
> {code}
> I executed two select quieries on each cluster:
> {code:sql}
> SELECT * FROM test.table1 where name='R1' AND class>0 AND class<4 AND inter='int1'
AND power=18 ALLOW FILTERING;
> SELECT * FROM test.table2 where name='R1' AND class>0 AND class<4 AND inter='int1'
AND foo='aa' ALLOW FILTERING;
> {code}
> On 2.1.14 and Trunk they where successful. But on 2.2.7 and 3.0.6 they failed, the first
one with {{InvalidRequest: code=2200 [Invalid query] message="Clustering column "inter" cannot
be restricted (preceding column "class" is restricted by a non-EQ relation)"}} and the second
one with {{InvalidRequest: code=2200 [Invalid query] message="Clustering column "foo" cannot
be restricted (preceding column "inter" is restricted by a non-EQ relation)"}}.
> I could get the queries to execute successfully on 2.2.7 and 3.0.6 by creating two more
2i:
> {code:sql}
> CREATE INDEX table1_inter ON test.table1 (inter) ;
> CREATE INDEX table2_foo ON test.table2 (foo) ;
> {code}
