Hi Garvit,
Are the consumers java? If so, can you take a thread dump every five
seconds for 30 seconds total for the affected consumer JVM?
Thanks,
Steve

I don't think that is the case. The lag is huge ~10^5 records.

Ok Garvit I still don't see the image but based on these inputs you
provided I'm thinking that the possible scenario could be that between two
polls from the consumer:
(a) the number of records added to the partitions already consumed in
previous poll is 500 or more (max.poll.records)

Hi Srinath,
I have attached the image.
The partitions belong to the same topic only. I have not explicitly set
max.partition.fetch.bytes or fetch.max.bytes or max.poll.records so it
should take the default values.
Let me know.
Thanks,

Hi Garvit,
Am unable to see the image you attached for some reason and am not able to
see if the partitions are in the same topic or in different topics.
Check if any of max.partition.fetch.bytes or fetch.max.bytes or
max.poll.records configured in your consumer is causing the behaviour.
Regards,
Is there a correlation between the lagging partitions and the consumer assigned
to them?

Hey Steve,
I have checked, count of messages on all the partitions are same.
I am still exploring an approach using which the root cause could be
determined.

Hi Garvit,
Are the slow partitions "hot", i.e., receiving a lot more messages than
others?

Just to add more details, these consumers are processing the Kafka events
and writing to DB(fast write guaranteed).
