Zusammenfassung:The invention discloses a key value storage system transmission method based on RDMA. According to the method, a memory key value storage system is combined with high-performance computing hardware RDMA, a fastest unilateral semantic RDMA write operation is adopted, GET and PUT instructions in the key value storage system are redesigned, the instructions and the data are packaged through a write command, data access is completed only through one-time round-trip transmission to avoid repeated round-trip transmission time delay caused by original read operation, and a bypass client kernel is adopted in the return stage to improve the upper-layer application experience of a client user. Meanwhile, aiming at the problem that read-write competition caused by operation of a bypass far-end kernelon a single side in the prior art cannot be uniformly scheduled, a priority queue is introduced into an RDMA memory of the server, and multi-client parallel instructions are converted into prioritized serial processing, so t
