Hey Andrew - +1 but I don't have a binding vote!
It took me a while to go through the KIP. Here are some of my notes during the reading: *Metrics* - Should we care about the client's leader epoch? There is a case where the user recreates the topic, but the consumer thinks it is still the same topic and therefore, attempts to start from an offset that doesn't exist. KIP-848 addresses this issue, but I can still see some potential benefits from knowing the client's epoch information. - I assume poll idle is similar to poll interval: I needed to read the description a few times. - I don't have a clear use case in mind for the commit latency, but I do think sometimes people lack clarity about how much progress was tracked by the auto-commit. Would tracking auto-commit-related metrics be useful? I was thinking: the last offset committed or the actual cadence in ms. - Are there cases when we need to increase the cadence of telemetry data push? i.e. variable interval. - Thanks for implementing the randomized initial metric push; I think it is really important. - Is there a potential use case for tracking the number of active partitions? The consumer can pause partitions via API, during revocation, or during offset reset for the stream. *Connections*: - The KIP stated that it will keep the same connection until the connection is disconnected. I wonder if that could potentially cause congestion if it is already a busy channel, which leads to connection timeout and subsequently disconnection.
