Thanks Jens! So assuming you've already paired your partition count to the consumer count...if you experience a spike in messages and want to spin up more consumers to add temporary processing capacity, what's the suggested way to handle this? (since it would seem you can't just add consumers as they would remain idle...and adding partitions appears to require manual rebalancing).
