RDMA Overview

This article is reprinted from Zhihu Column: 1. RDMA Overview, Author: Savir. I originally intended to complete this overview entirely in my own words, but the beginning was not as easy to write as I imagined. It seems that summarizing a technology from a macro perspective is much more difficult than exploring the details from a micro perspective. This article mainly introduces the RDMA technology as explained by others, with some of my own understanding added. As the content of this column increases, this overview will also be updated and gradually improved.
