Storing connected clients - websockets
Storing connected clients - websockets
Hello, I'm developing application which uses websockets for chatting feature.
I was wondering what is best way to store all client handles in server side. Every tutorial (eg. this) just says to store in some form of map. I figured that in large commercial apps list of clients would be rather high and I wondered if storing it on heap is actually valid implementation or if some other solutions like caching dbs like redis are used.
What's your experience with that?
You're viewing a single thread.
Why do you want to store them? I used socket.io in one app and I used channels to manage who gets what but disconnects/reconnects would happen often so I didn't use the connection directly, but emitting messages to clients currently subscribed to a given channel.
Agents log into the dashboard - connect and the server subscribes them to the "agents" channel to which ticket list items messages are emitted. Clicks on a ticket - that's a ticket_id unique channel to which he gets subscribed. Any disconnect/reconnect would create a new connection, the old one is dropped and the agent is once again subscribed to these channels based on where in the dashboard he is in.
