Many Server Load balancer algorithms are available for application scenarios, including Round Robin and HASH) least Connection, Response Time, and Weighted. Hash algorithms are the most commonly used algorithms. A typical application scenario is

Two key issues need to be solved for implementing consistent hash algorithms. One is the selection of data structures used for node storage and search, and the other is the selection of node hash algorithms. First, let's talk about the data
