Neha Narkhede commented on KAFKA-671:
-------------------------------------
Nullifying the request object seems like a bigger change. I'm wondering about
the precise impact to GC that these changes will introduce. If the impact is
just that the objects get garbage collected within 1 iteration of the young gen
collector VS 2-3 iterations, I would say the performance upside of this change
is not worth the risk. But if it significantly reduces garbage collected
overhead, it might be worth looking further into. Even if we have to do this, I
agree with Sriram that his earlier change is smaller impact than nullifying
request object and caching a bunch of things to get around it.
