django channel save chat record upon last user leave the room
Hi I am new to any Async coding hence the great django-channels official lib is a bit obfuscated to me.
I was able to define a ORM process upon message send to save the message to db. That will be easy.
However, imagine 5000 users sending messages simultaneously. The db will easily be overloaded even if I use a celery task queue. Plus the db could easily accumulate millions of rows in a short period.
I imagine there to be a way to gather all lingering messages in the channel-layer, and upon layer close (last user exit, websocket connection = 0), save these into a JsonField as one row?
TLDR: how to check layer termination, and after that how to get all messages sent? Where are they stored, in memory?
Current thought on a naive method: create a memory register (like database, but in memory only) for each channel and place all messages there as they sent. Then when the websocket terminates, trigger a save code. But then, how to create this kind of fake-db that only exist in memory?
Appreciate all suggestions!
