Hi [~becket_qin],
can i pack this issue?
my solution is to add a methed named indexOfSubtask to interface SourceReaderContext,as following
{code:java}
/**
* @return The index of this subtask
*/
int getIndexOfSubtask();{code}
And then ,implement this method in the open() method of class SourceOperator,as following
{code:java}
@Override
public int getIndexOfSubtask(){
return getRuntimeContext().getIndexOfThisSubtask();
}
{code}
what do you think of it ?

> It is useful for the `SourceReader` to retrieve its subtask id. For example, Kafka readers can create a consumer with proper client id.
