@dujian0068 -- you should send a final email to the VOTE thread calling the vote closed and accepted (also summarizing the vote result), and update the KIP wiki pages accordingly. Thanks.

@mjsax Thank you review:
Do you mean the documentation that needs to be updated is in the https://github.com/apache/kafka-site project?

[mjsax]

No. The doc changes just go into kafka.git as part of this PR -> https://github.com/apache/kafka/tree/trunk/docs/streams

kafka-site.git will only be updated during the next release -- you don't have to worry about this part.

Thanks for the KIP and contribution @dujian0068!

Overall this looks good, I have one minor comment.

Thank you @mjsax
I have updated config-stream doc. Do I need to update upgrade-guide? Can you tell me in which cases I need to update upgrade-guide?
