Sagar Rao commented on KAFKA-8238:
----------------------------------
Thanks [~cmccabe]. I started looking at the code to analyse what needs to be
done.
1 thing that I wanted to know is that, is this feature something that needs to
be enabled only for newer version(specifically for magic numbers = 2)? If
that's the case, then I think we can compute the bytes and message read within
the iterator:
[https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/coordinator/group/GroupMetadataManager.scala#L557]
> Log how many bytes and messages were read from __consumer_offsets

> We should log how many bytes and messages were read from __consumer_offsets.
> Currently we only log how long it took. Example:
> {code}
> [GroupMetadataManager brokerId=2] Finished loading offsets and group metadata
> from __consumer_offsets-22 in 23131 milliseconds.
> {code}
