------------------------------------------------
Yes. It can be done with offheap because from the netty buffers we tend to
copy the requests to onheap buffers. Instead now you will need to just copy to
the buffers from the pool. seeing the private impl of [~aoxiang] - that is what
was being done. So should work fine along with the benefits that they have seen
with netty by running in prod for 2 months.
