> Using Cassandra 1.2.11, the following sequence demonstrates the issue:
> {code:sql}
> CREATE TABLE blah (key text, column text, value text, PRIMARY KEY (key, column)) WITH COMPACT STORAGE;
> INSERT INTO blah (key, column, value) VALUES ('a', 'a', 'a');
> INSERT INTO blah (key, column, value) VALUES ('a', 'b', 'e');
> INSERT INTO blah (key, column, value) VALUES ('a', 'c', 'e');
> INSERT INTO blah (key, column, value) VALUES ('a', 'd', 'e');
> INSERT INTO blah (key, column, value) VALUES ('a', 'e', 'e');
> SELECT column FROM blah WHERE key = 'a' AND column < 'c' ORDER BY column DESC LIMIT 2;
>  column
> --------
>       b
> {code}
> However I would expect columns b and a to both be returned. Only seems to be an issue if the range bound is an exact match, and only if ORDER BY column DESC is used.
