Tsz-wo Sze commented on RATIS-2096:
-----------------------------------

Heap memory and non-heap memory are not interchangeable.  Not sure if there are 
applications prefer to have a larger heap.

Anyways, we may keep this JIRA open but not changing anything.  If there is a 
need in the future, we will change the code at that time.

> Add a conf to enable/disable zero copy.
