[VOTE] KIP-447: Producer scalability for exactly once semantics

[Boyang Chen]

Hey all,

I would like to start the vote for KIP-447
<https://cwiki.apache.org/confluence/display/KAFKA/KIP-447%3A+Producer+scalability+for+exactly+once+semantics>.
This is a very important step to improve Kafka Streams scalability in
exactly-once semantics, by avoiding linearly increasing number of producers
with topic partition increases.

Thanks,
Boyang
