Reach stacker

Provided are a method and system for achieving high availability of service under a high-load scene in a distributed system. The method includes constructing a node selection model at a master node of a distributed cluster; constructing a request selection model in each slave node; wherein the request selection model includes weights of designated requests and trade-off parameters set for requests each having a weight greater than a set value; when the distributed system enters the high-load scene, reading, by the master node, the node selection model, and sequentially selecting the served slave nodes according to a time slice round robin policy; and reading, by each slave node, the request selection model, and sequentially returning data of each request according to the trade-off parameters of each request.
