Description

This Jira is created based on arp comment on HDDS-1856.

Also we should probably add for the existing fields. I think some ASCII art description of how double buffer works will be helpful to future maintainers. However it's okay to file a follow up jira and do separately later. Don't need to do it for this commit.
