--------------------------------------
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 indexOfSubtask();{code}
And then ,implement this method in the open() method of class SourceOperator,as
following
{code:java}
@Override
public int indexOfSubtask(){
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.
