WebFour Types of RDMA Operations •RDMA Write: Write data from local node to specified address at remote node. •RDMA Read: Read data from specified address at remote node … Webthe use of RDMA to read-only service requests, namely gets, while letting the server handle all other requests via traditional messaging. As practical key-value work-loads tend to be dominated by read operations [1], this approach can capture most of RDMA’s performance benefits while facilitating a much simpler design than
