Hello, I apologize for the lack of clarity in the question, this is a new area we are exploring.
Frankly speaking, we would love to know the answer to both. I have read that there is an upper limit to partitions, 200k with zookeeper and 2mill with Kraft, but I have not found anything if there is a correlation between topics. This also goes for the isolate permissions to name spaces is there a correlation between the partition limit here and the limit allowed for this feature? Kenneth Eversole
