does the real time messaging use pooling? does every connected user must “fetch” new data?
All our SDKs take care about getting new messages, take a look at the doc https://backendless.com/docs/js/pubsub_message_listener.html
I’m not sure what do you mean, could you please describe your goal in details?
so i must use a client SDK to get the benefits?
yeah, without our SDK it won’t work
using only codeless on the server will not be enough?
Codeless works on the server, and it has an invocations time limit, but for RealTime we must have a live subscription which will be subscribed to our RealTime server over sockets.
But you are able to send messages from BusinessLogic.
in my mobile app i use ajax to post and get data from backendless and i use codeless on the server.
so i was hoping that i can keep using the same approach for the real time messaging.
