All the data is stored on Postgres. The first render shows dummy data. As soon as liveview connection is established, we fetch data from postgres, and current user on the website count(using Presence) and update the client. Liveview also subscribes(through Phoenix PubSub) to a particular topic(with "update:" prefix) to get some updates.
Whenever data is updated(a new user visits my website/blog), we send a pubsub message to a that "update:" topic. The liveview gets a message on this topic, fetches latest data from redis and presence count, and updates the liveview.
