Hi, I'm upgrading a kafka streams application from 0.10.2.1 to 0.11.0.1, running against a kafka cluster with version 0.10.2.1. The application uses a couple of state stores.
When stopping/starting the application prior to the upgrade (with 0.10.2.1 client) on 2 instances, it was up and running in less than 30s to a minute on all nodes. However, after client was upgraded to 0.11.0.1, when the instances started (during some load), it took about 6 minutes for one of the nodes to reach "RUNNING" state, and the second one didn't get there. After 10 minutes I had to roll back. Is it expected that this initial rebalancing takes a little longer with 0.11.0.1, and is there a way to configure or tweak the client, or otherwise optimize this to make this go faster? Thanks, Johan
