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

             Summary: DELETE CAS on 'primary key only' table
                 Key: CASSANDRA-5832
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5832
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 2.0 beta 2
            Reporter: Blair Zajac
            Priority: Minor


Following up on the "CAS on 'primary key only' table" issue [1] which added 
support for atomically creating a primary key only table, this ticket is 
requesting support for a CAS DELETE of a row from such a table.

Currently these two different statements fail:

Trying "DELETE FROM test1 WHERE k = 456 IF EXISTS" using cassandra-dbapi2:
cql.apivalues.ProgrammingError: Bad Request: line 0:-1 no viable alternative at 
input '<EOF>'

Trying "DELETE FROM test1 WHERE k = 456 IF k = 456"
cql.apivalues.ProgrammingError: Bad Request: PRIMARY KEY part k found in SET 
part
