------------------------------------
Summary: 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
Reporter: Roman Shtykh
Assignee: Roman Shtykh
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.
