--------------------------------
> Ignite Kafka sink connector should have an option to transform Kafka values
> ---------------------------------------------------------------------------
>
> Key: IGNITE-4198
> URL: https://issues.apache.org/jira/browse/IGNITE-4198
> Project: Ignite
> Issue Type: Improvement
> Components: streaming
> Affects Versions: 1.7
> Reporter: Roman Shtykh
> Assignee: Roman Shtykh
> Labels: community, streaming
> Fix For: 1.8
>
>
> Currently the connector takes a Kafka key and uses it as an Ignite key.
> However, Kafka keys can be null, and users may want to specify an Ignite key
> from the value object.
> Instead of creating a new transformer interface, I think we can use
> {{StreamMultipleTupleExtractor}} whenever its implementation is specified by
> the user in connector config file.
