Hey guys, I am implementing a Chat System for a very large school group. The requirements are:
Every user must be “friend” of other users (It is not necessary add new connections);
There are groups, Teachers, Managers, Students …
I thought the following: I create the groups, add the users in their respective groups and share the contacts between them.
But what to do with the offline users? XMPP send a list with every contact, offline or online on connection (Correct me if I am wrong).
I am talking about 30 thousands users, yes it is a huge amount.
Do you have any suggestions?
Thank you very much.
