Thank you for the response. But the reference does not seem to be answering any 
of those questions.

Hi all,

I'm wondering if dynamic resource allocation works in spark+kafka streaming 
applications. Here're some questions:
Will structured streaming be supported?
Is the number of consumers always equal to the number of the partitions of 
subscribed topic (let's say there's only one topic)?
If consumers is evenly distributed across executors, will newly added 
executor(through dynamic resource allocation) trigger a consumer reassignment?
Would it be simply a bad idea to use dynamic resource allocation in streaming 
app, because there's no way to scale down number of executors unless no data is 
coming in?
Any thoughts are welcomed.
