Sessions on socket.io in node.js?

Question

Node.js

I started digging into node js, please tell me how to remember the user in socket.io? It is possible to send to a specific person by his id, but this id is new after each reboot. How to organize this?

Store in a database (redis/mongo/leveldb/mysql) or write/read from a file.
