names, so hosts files could be said to be relatively simple databases. However, as the network exploded, A hosts file, a server, and a group of DNS clusters cannot hold more and more host requests. Therefore, a distributed database has emerged, which is used to cut a database into n slices, resolve client requests on different hosts. When different hosts need to be resolved, they are implemented on differe
