Yuki Morishita commented on CASSANDRA-3680:
-------------------------------------------
hmm, filtering with key and 2I works, but this time I get wrong value for key.
{code}
cqlsh:3680> select * from blogs;
blog_id | posted_at | author | content
---------+--------------------------+--------+---------
1 | 2012-11-11 00:00:00-0600 | foo | bar
2 | 2012-11-12 00:00:00-0600 | foo | baz
3 | 2012-11-11 00:00:00-0600 | qux | quux
cqlsh:3680> select * from blogs where author='foo' and posted_at = '2012-11-11';
blog_id | posted_at | author | content
---------+--------------------------+--------+---------
2 | 2012-11-11 00:00:00-0600 | foo | bar
{code}
blog_id should be '1'.
{code}
cqlsh:3680> select * from blogs where author='foo';
blog_id | posted_at | author | content
---------+--------------------------+--------+---------
2 | 2012-11-11 00:00:00-0600 | foo | bar
2 | 2012-11-12 00:00:00-0600 | foo | baz
{code}
Here, something is wrong with first row in result set.
> Add Support for Composite Secondary Indexes

> Key: CASSANDRA-3680
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3680
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: T Jake Luciani
> Assignee: Sylvain Lebresne
> Labels: cql3, secondary_index
> Fix For: 1.2
>
> Attachments: 0001-Secondary-indexes-on-composite-columns.txt
>
>
> CASSANDRA-2474 and CASSANDRA-3647 add the ability to transpose wide rows
> differently, for efficiency and functionality secondary index api needs to be
> altered to allow composite indexes.
> I think this will require the IndexManager api to have a
> maybeIndex(ByteBuffer column) method that SS can call and implement a
> PerRowSecondaryIndex per column, break the composite into parts and index
> specific bits, also including the base rowkey.
> Then a search against a TRANSPOSED row or DOCUMENT will be possible.
