问题 I develop mobile social network. All data stored in MySQL (via shards). Hot data stored in Redis, and there is shards map in Redis too. Backend = node.js (express) What is the right way of fast requests to a different MySQL servers within one request to the back-end from mobile client? Example: The client requests the server to the user profile with id = 1, which we store on the server mysql-1 shard #1. At the same moment another client requests the server to the user profile with id = 2,
