> 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
> Reporter: Jakub Nowacki
> Assignee: Aleksandr Salatich
> Priority: Major
> Labels: auto-unassigned, pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
