Hello,
I’m making a demo app for bidding. It is a POC for channels and now I decided to try to persist data using Mnesia. First thing is that I’m struggling with decision whether to use Amnesia wrapper or Mnesia directly… (but thats off-topic)
The main thing is that before the idea of persisting data I designed the app so that each item that yet to be/is auctioned should rest in dedicated GenServer and users (via websockets) will place_bids from channels by issuing message to dedicated GenServer for given auction item. I thought this solution might be a good idea to leverage the parallelism of ErlangVM. But now with Mnesia I feel like I dont need individual GenServers because I can directly access Mnesia data… Am I correct? I also thought of preserving the idea of individual GenServers that would keep the state of the auction item but would periodically/by debounce “flush” the state to Mnesia… (but that would probably open space for potential loss of unsaved data) Is that dumb idea?
Or would any other approach fit here better?

Thanks in advance!
