Subject [jira] [Commented] (CASSANDRA-8147) Secondary indexing of map keys does not work properly when mixing contains and contains_key
Date Fri, 31 Oct 2014 21:48:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14192560#comment-14192560
] 

Tyler Hobbs commented on CASSANDRA-8147:
----------------------------------------

bq. Relation.Type and IndexExpression.Operator are really similar. Should we merge them?

I think that's a good idea, if you're willing to do it (perhaps as a second patch, for clarity).

bq.  in which package do you think that we should put the resulting class?

I'm tempted to just use Relation.Type, but if you think that's a bad idea for some reason,
I would make an o.a.c.cql3.Operator class.

> If you have a table with a map column and an index on the map key selecting data using
a contains key and a contains will not return the expected data.
> The problem can be reproduced using the following unit test:
> {code}
>     @Test
>     public void testMapKeyContainsAndValueContains() throws Throwable
>     {
>         createTable("CREATE TABLE %s (account text, id int, categories map<text,text>,
PRIMARY KEY (account, id))");
>         createIndex("CREATE INDEX ON %s(keys(categories))");
>         execute("INSERT INTO %s (account, id , categories) VALUES (?, ?, ?)", "test",
5, map("lmn", "foo"));
>         assertRows(execute("SELECT * FROM %s WHERE account = ? AND id = ? AND categories
CONTAINS KEY ? AND categories CONTAINS ? ALLOW FILTERING", "test", 5, "lmn", "foo"), row("test",
5, map("lmn", "foo")));  
>     }
> {code}
