Consumer group suggestion: minimum consumer count

With Kafka Streams, it's common to spin up and shut down clusters of consumers by performing a graceful shutdown and restart during a deploy. One thing we've been running into is that during the startup and shutdown of a kafka streams clusters you often can have multiple rebalances as the consumer

Re: [DISCUSS] KIP-168: Add TotalTopicCount metric per cluster

Hi Abhishek, Thanks for your response. Even though, as you suggested, this metric can be calculated using other present metrics, I still feel that adding the 'number of partitions' metrics helps in better representing a Kafka cluster. I don't feel too strong about it though (in case it is

Re: [DISCUSS] KIP-168: Add TotalTopicCount metric per cluster

Hi Vahid, Thanks for the response. Kafka currently has a partition leader count metric per broker. The total partition count metric can be built by summing the partition leader count across the cluster. This information may not be consistent but it'll be eventually consistent in steady state.
