>                 Key: FLINK-5080
>                 URL: https://issues.apache.org/jira/browse/FLINK-5080
>             Project: Flink
>          Issue Type: Bug
>          Components: Connectors / Cassandra
>    Affects Versions: 1.1.3

>            Priority: Major
>              Labels: pull-request-available
> When a record is saved to Cassandra it may return a ResultSet to the callback given in
the saveAsync; e.g. when we do {{INSERT ... IF NOT EXISTS}}, a ResultSet is returned with
column {{applied: false}} if the record exists and the new record has not been inserted. Thus,
we loose data in such case. 
> The minimal solution would be to log the result. The best solution would be to add possibility
of passing a custom callback; in this way we could deal with a success or failure in more
custom way.  Other solution is to add a possibility to pass onSuccess and onFailure functions,
which would be executed inside the callback.
