Review Comment:
Curious, can this even be null?

Review Comment:
This is current offset right?

Review Comment:
This comment applies to time based reporting as well and can be taken as
follow up.
Should this belong to individual consumer types instead of common code just
like how getCurrentPartitionLagState is interfaced out, because reporting the
metric for all types here might not make any sense ?
Like you said, only for Kafka, this is relevant.

Review Comment:
What are other types that can fall here? Basically we need to be able to
explain this metric.
