Hi Wei,
I'm assuming the lastModified time is when latest hard commit happens. Is
that correct?
>> Yes. its correct.
I also see sometime difference between replicas and leader commit
timestamps where the "diff/lag < autoCommit interval". So in your case you
noticed like upto 10 mins.
My guess is due to different start time of these replica/leader node, their
commit may happen at different times and thus you would see the difference.
Thanks,
Susheel
