             Summary: Support per-connector converters
                 Key: KAFKA-3845
                 URL: https://issues.apache.org/jira/browse/KAFKA-3845
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 0.10.0.0
            Reporter: Ewen Cheslack-Postava
            Assignee: Ewen Cheslack-Postava
            Priority: Critical
             Fix For: 0.10.1.0


While good for default configuration and reducing the total configuration the 
user needs to do, it's inconvenient requiring that all connectors on a cluster 
need to use the same converter. It's definitely a good idea to stay consistent, 
but occasionally you may need a special converters, e.g. one source of data 
happens to come in JSON despite you standardizing on Avro.

Note that these configs are connector-level in the sense that the entire 
connector should use a single converter type, but since converters are used by 
tasks the config needs to be automatically propagated to tasks.

This is effectively public API change as it is adding a built-in config for 
connectors/tasks, so this probably requires a KIP.
