Thanks @oscerd! I think a very useful sample would show how to create a
`DataSet` that took into consideration the incoming payload. Here's the
snippet I was trying to get to work [1]. I couldn't get my `DataSet` to be
registered. Keep getting this error [2].
**[1]**
```java
public class FlinkSample extends RouteBuilder implements Processor {
@Override
public void configure() throws Exception {
// Receive a msg from the configured Kafka topic
from("timer:foo")
.log("Received body: ${body}")
.split(body().tokenize("\n"))
.process(this)
.to("flink:dataSet?dataSet=#myDataSet&dataSetCallback=#myDataSetCallback")
.log("Response body: ${body}");
}
@BindToRegistry
public DataSetCallback<String> myDataSetCallback () {
return new DataSetCallback<String>() {
@Override
public String onDataSet(DataSet ds, Object... payloads) {
return "this is the result";
}
};
}
@Override
public void process(Exchange exchange) throws Exception {
final ExecutionEnvironment env =
ExecutionEnvironment.getExecutionEnvironment();
DataSet<String> myDataSet =
env.fromElements(exchange.getIn().toString());
exchange.getContext().getRegistry().bind("myDataSet", DataSet.class,
myDataSet);
}
}
```
