Hi all,

I wonder whether limitations mentioned in [1] regarding Kafka scalability 
in number of topics are still valid. For example, did the recent changes 
in the design around usage of ZooKeeper versus internal membership 
protocol affected the scalability - one way or the other?
Also, it seems that the introduction of Kafka Streams may increase the 
number of topics (including those created by the app, and those created 
internally by KS), and maybe also change a bit the usage pattern in 
general (if large portion of the load is generated by KS). Are there any 
performance numbers (e.g., for table-based APIs), known bottlenecks 
(specific to KS), tuning recommendations?

Thanks,
Alex
