Comparing Professional and Basic Editions
Huawei Cloud DCS professional edition is completely developed by Huawei Cloud, and compatible with open-source Redis software. This edition uses the multi-thread master-N*worker model instead of the conventional master-worker model. Each worker thread can listen on ports to monitor requests for establishing network connections, accept the requests and establish network connections, read and write data (in network connections, for example, sockets), and parse and process Redis commands. As a result, performance is improved by N times.
