Subject [jira] [Commented] (CASSANDRA-8275) Some queries with multicolumn relation do not behave properly when secondary index is used
Date Wed, 04 Feb 2015 14:29:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14305152#comment-14305152
] 

Benjamin Lerer commented on CASSANDRA-8275:
-------------------------------------------

{quote}In 2.0, this appears to cause a regression in the dtest CQLTests.simple_tuple_query_test().
It throws an IRE when the query should be supported. I'm not sure if we need CASSANDRA-8613
applied at the same time to fix this.{quote}

I had a look at the test and the failing query is effectively caused by  CASSANDRA-8613. I
am working on it and it should be ready in a couple of days.

{quote}Also in 2.0, in the dtest CQLTests.composite_index_with_pk_test(), we're not requiring
ALLOW FILTERING (where I believe we should be), causing a test to fail.{quote}

The patch was effectively introducing a regression.

> In the case where we perform a select using a multicolumn relation over multiple columns
that use a secondary index the error message returned is wrong.
> The following unit test can be use to reproduce the problem:
> {code}
>     @Test
>     public void testMultipleClusteringWithIndex() throws Throwable
>     {
>         createTable("CREATE TABLE %s (a int, b int, c int, d int, PRIMARY KEY (a, b,
c, d))");
>         createIndex("CREATE INDEX ON %s (b)"); 
>         
>         execute("INSERT INTO %s (a, b, c, d) VALUES (?, ?, ?, ?)", 0, 0, 0, 0);
>         execute("INSERT INTO %s (a, b, c, d) VALUES (?, ?, ?, ?)", 0, 0, 1, 0);
>         execute("INSERT INTO %s (a, b, c, d) VALUES (?, ?, ?, ?)", 0, 0, 1, 1);
