Hi Abhishek, - Correct on connecting to external stores. You can use Kafka Connect to get things in or out. (Note that in the 0.10.1 release KIP-67 allows you to directly query Kafka Stream's stores so, for some kind of data you don't need to move it to an external store. This is pushed in trunk.)
- You can definitely use more threads than partitions, but that will not buy you much since some threads will be idle. No two threads will work on the same partition, so you don't have to worry about them repeating work. Hope this helps.
