Description

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
