list consumer lag per topic-partition and consumer-group

[michael-elly]

Description

Hi, Looking for how to list consumer gap using the .NET API I was finally able to do it for a given topic and a consumer group. I can derive the partitions from the topic and then per consumer group find the lag. I was not able to do it per consumer group name only (cannot find the associated topics with a given consumer group name). See my query on stackoverflow: https://stackoverflow.com/questions/60506580/how-can-i-list-the-kafka-consumer-lag-and-latest-offset-per-partition-and-consum

How to reproduce

is there any chance to link topics with consumer groups using SDK?
