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

             Summary: BATCH with multiple CAS operations should return add information which DML failed
                 Key: CASSANDRA-7420
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7420
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Robert Stupp


A {{BATCH}} like this

{noformat}
BEGIN BATCH
  INSERT INTO foo (id, num) VALUES (42, 11);
  INSERT INTO bar (id, num) VALUES (42, 11);
APPLY BATCH;
{noformat}

Should not only return {{[applied]=false, id=42, num=11}} but also for example the index of the failed statement in the batch. This allows better error handling on the client.
