My app should the following needs:
1.be able to communicate in real time with browser, iOS, and Android native apps.
2.one user can send messages to another user in private
3.users can chat in serval chat room at a time
4.once a message is sent, it should be push to target user in realtime.
5.has a retry mechanism to guarantee delivery and messages should store in db like mysql
Is django channels suite my requirements? Is there a limit amout of channel or is that what I need to do is create a group for each online user including ios and android ones?
What my thought is using redis to cache the messages and store in MySQL, use celery to handle message store and distribute.
Anyone could give some advices?
