-----------------------------------------

             Summary: LIMIT fetches one less than requested value
                 Key: CASSANDRA-6330
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6330
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Branden Visser


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.
